Single Digit Representations of
Natural Numbers From 1 to 5000
Inder J. Taneja1
Abstract
There are different ways of representing natural numbers, such as writing in terms of 1 to 9 or 9 to 1, writing in terms of single
letter, single digit, flexible power, etc. These types of representations we call as crazy representations. This paper extends the authors
previous work [8] on representation of natural numbers in terms of single digit. The previous work is upto 1000. This paper bring
numbers 1 to 5000 in terms of each digit. The total work up to 20000 numbers divided in four parts. For other parts refer [9, 10, 11].

1.1 First Type: Increasing and Decreasing
In 2014, author [1] wrote natural numbers in increasing and decreasing orders of 1 to 9 and 9 to 1. See examples below:
100 := 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 × 9 = 9 × 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1
101 := 1 + 2 + 34 + 5 + 6 × 7 + 8 + 9
= 9×8+7+6+5+4+3×2+1
102 := 12 + 3 × 4 × 5 + 6 + 7 + 8 + 9
= 9 + 8 + 7 + 6 + 5 + 43 + 2 + 1
103 := 1 × 2 × 34 + 5 + 6 + 7 + 8 + 9
= 9 + 8 + 7 × 6 + 5 × 4 + 3 + 21
104 := 1 + 23 + 4 + 5 + 6 + 7 × 8 + 9
= 9 + 8 + 7 + 65 + 4 × 3 + 2 + 1
105 := 1 + 2 × 3 × 4 + 56 + 7 + 8 + 9
= 9+8×7+6×5+4+3+2+1
106 := 12 + 3 + 4 × 5 + 6 + 7 × 8 + 9
= 9+8×7+6×5+4+3×2+1
107 := 1 × 23 + 4 + 56 + 7 + 8 + 9
= 9 + 8 + 76 + 5 + 4 + 3 + 2 × 1
108 := 1 + 2 + 3 + 4 + 5 + 6 + 78 + 9
= 9 + 8 + 76 + 5 + 4 + 3 + 2 + 1.
See more examples,
999 := 12 × 3 × (4 + 5) + (67 + 8) × 9
2535 := 1 + 2345 + (6 + 7 + 8) × 9
= 9 + 8 + 7 + 654 + 321.
= 9 + 87 × (6 + 5 × 4 + 3) + 2 + 1.
2607 := 123 × 4 × 5 + 6 + (7 + 8) × 9
= 987 + 6 × 54 × (3 + 2) × 1.

10958 := 12 × 3 + 4 + 5! × (67 + 8 × 9) = (9 + 8 × 7 × 65 + 4) × 3 − 2 + 1.
= − 9 + 8 + 7 × (6 + 5) × (4 × 3)2 × 1.
11807 := 1 × 234 × (5 + 6 × 7) + 89
We observe that the number 10958 is the only number among 0 to 11111, where we need extra operations, such as
square-root, factorial, etc. to write in increasing case. For more details refer author’s web-site link [5]. Extension of
numbers from 11112 to 30000 refer [2, 3, 4].
1.2 Second Type: Flexible Power Representations
Let us consider two numbers, 1 and 2. Using the idea of power and the operations of addition and subtraction, we can
write following 3 numbers in terms of 1 and 2, as 1 = −12 + 21 , 3 = 12 + 21 and 5 = 11 + 22 . In this situation, we observe
that bases and exponents are of same digits. Permutations of exponent values helps in bringing different numbers. In
case of repeated values, for example, 3 = 12 + 21 = −11 + 22 , only possibilities is considered. There is only one number
having single digit, i.e., 1 = 11 . For simplicity, let us represent the above procedure as (1, 2)(1,2) , resulting in three possible
values. The above procedure is with two digits. Instead having two digits, we can work with two letters, such as,
(a, b)(a,b) , ...(a, b, c, d , e, f , g , h, i )(a,b,c,d ,e, f ,g ,h,i ) ,
where a, b, c, d , e, f , g , h, i ∈ {1, 2, 3, 4, 5, 6, 7, 8, 9}, all distinct.

100 := 26 + 62
107 := −12 + 27 − 33 + 71
114 := −22 + 35 − 53
101 := 11 + 26 + 62
108 := 17 + 26 + 62 + 71
115 := 15 − 21 − 32 + 53
102 := −25 + 32 + 53
109 := 12 + 27 − 33 + 71
116 := 22 + 35 − 44 + 53
103 := 11 − 25 + 32 + 53
110 := 19 + 26 + 62 + 91
117 := −11 + 35 − 53
104 := −11 + 23 + 34 + 42
111 := −13 + 27 − 32 − 71
118 := 35 − 53
105 := 23 + 34 + 42
112 := 35 − 44 + 53
119 := 11 + 35 − 53 .
106 := 27 + 33 − 72
113 := −15 − 21 − 32 + 53
See more examples,
638 := −15 − 21 − 42 + 54
6922 := −36 − 53 + 65
666 := −25 + 32 + 43 + 54
9711 := 13 + 24 + 38 + 42 + 55 − 81
786 := −14 + 36 + 43 − 61
9777 := 19 + 21 + 47 − 72 − 94
1933 := −13 − 22 + 37 − 44 + 71
11110 := 11 + 22 + 39 − 56 + 65 − 93
1934 := 29 + 36 − 62 + 93
11111 := −11 + 27 + 38 − 42 + 73 + 84 .
3098 := −33 + 55
2280 := −11 − 26 + 45 + 52 + 64
The whole work is from 1 to 11111. For details refer [6].
1.2.2 Equal String Lengths
Based on second type still we can write natural numbers in a sequential way with uniform representations. Instead
working with unequal strings as of previous section, here we worked with equal string using the digits 0 to 9, i.e., using
all the 10 digits, {0,1,2,3,4,5,6,7,8,9}. The results obtained are symmetric, i.e., writing in 0 to 9 or 9 to 0, the resulting
number is same. See some examples below,
201 := 03 + 19 + 24 + 37 − 48 + 51 + 66 + 75 + 82 + 90
212 := 05 + 17 − 28 − 39 + 41 + 56 + 60 + 73 + 84 + 92
202 := 00 + 19 + 26 + 38 − 47 + 55 + 63 + 72 + 81 + 94
213 := 05 + 18 − 27 − 39 + 41 + 56 + 63 + 70 + 84 + 92
203 := 03 − 19 + 24 + 37 − 48 + 50 + 66 + 75 + 82 + 91
214 := 05 + 17 − 28 − 39 + 40 + 56 + 61 + 73 + 84 + 92
204 := 08 + 19 + 25 + 37 − 46 + 51 + 64 + 72 + 80 + 93
215 := 05 + 19 + 28 + 37 − 46 + 50 + 64 + 72 + 83 + 91
205 := 03 + 19 + 24 + 37 − 48 + 50 + 66 + 75 + 82 + 91
216 := 01 − 17 + 28 − 39 + 45 + 56 + 60 + 74 + 83 + 92
206 := 07 − 19 − 25 − 38 + 46 + 51 + 63 + 74 + 80 + 92
217 := 07 − 19 + 25 − 38 + 46 + 52 + 63 + 74 + 81 + 90
207 := 08 + 19 + 25 + 37 − 46 + 50 + 64 + 72 + 81 + 93
218 := 01 + 17 + 28 − 39 + 45 + 56 + 60 + 74 + 83 + 92
208 := 07 + 19 − 25 − 38 + 46 + 51 + 63 + 74 + 80 + 92
219 := 07 + 19 + 25 − 38 + 46 + 52 + 63 + 74 + 81 + 90
209 := 07 − 19 − 25 − 38 + 46 + 50 + 63 + 74 + 81 + 92
220 := 07 + 19 + 25 − 38 + 46 + 52 + 63 + 74 + 80 + 91 .
210 := 05 − 17 − 28 − 39 + 41 + 56 + 60 + 73 + 84 + 92
211 := 07 + 19 − 25 − 38 + 46 + 50 + 63 + 74 + 81 + 92

11080 := 08 + 19 + 27 + 36 + 42 + 55 + 60 + 71 + 83 + 94
11081 := 08 − 19 + 26 + 37 + 44 + 51 + 65 + 70 + 82 + 93
11082 := 08 + 19 + 26 + 37 + 41 + 54 + 65 + 73 + 80 + 92
11083 := 08 + 19 + 26 + 37 + 44 + 51 + 65 + 70 + 82 + 93
11084 := 07 + 19 + 28 + 36 + 41 + 55 + 60 + 73 + 82 + 94
11085 := 08 + 19 + 26 + 37 + 44 + 50 + 65 + 71 + 82 + 93
11086 := 07 + 19 + 28 + 36 + 40 + 55 + 61 + 73 + 82 + 94
11087 := 06 + 19 − 28 + 37 + 42 + 54 + 65 + 70 + 81 + 93 .
The whole work is from 1 to 11111. For details refer [7].
Analysing the procedures given in sections 1.1 and 1.2 , we observe that in section 1.1 , all the 9 digits are used in
increasing and decresing ways to bring natural numbers, where each digit appears only once. In this case, the operations
used are, addition, subtraction, multiplication, division, potentiation, factorial and square-root. The section 1.2
works with representations of natural numbers written in a way that we use each digit twice, where bases and exponents
are of same digits with different permutations. Subsection 1.2.1 choose the digits from 1 to 9, according to necessity,
while subsection 1.2.2 works with all the 10 digits, i.e., 0 to 9, along with the operations of addition and subtraction.
1.3 Third Way: Single Digit Representations
In [1], author wrote natural numbers 1 to 1000 using single digit in each case. For example,
995 := (11 − 1)(1+1+1) − (11 − 1)/(1 + 1)
717 := (1 + 1)11 − 11(1+1+1)
:= 222 + 222 + 22/2
:= 22 + 2 × (222 + 2) + 2/2
:= 3(3+3) − 3 − 3 × 3
:= 3 × 333 − 3 − 3/3
:= 4 × (4 × 44 + 4) − 4 + 4/4
:= 4 × (44 − 4 − 4) + 4 − 4/4
:= (55 × (55 + 5 + 5) + 5 + 5)/5
:= 5 × (5 + 5) × (5 × 5 − 5) − 5
:= (6 × 6/(6 + 6))6 − 6 − 6
:= 666 + 6 × 66 − 66 − 6/6
:= 777 − 7 × 7 − 77/7
:= (7 + 7) × (77 − 7) + 7 + 7 + 7/7
:= 8 × 88 + (88 + 8 + 8)/8
:= 888 + 88 + 8 + 88/8
:= 9 × 9 × 9 − (99 + 9)/9.
:= 999 − (9 + 9 + 9 + 9)/9.
1000 := (11 − 1)(1+1+1)
786 := ((1 + 1 + 1)(1+1+1) + 1)(1+1) + 1 + 1
:= (22 + 2 + 2 + 2)2 + 2
:= 2 × (222 + 2(2+2) )
:= 33 × (33 − 3) − 3 − 3
:= (3 × 3 + 3/3)3
:= 4 × (4 × (44 + 4) + 4) + (4 + 4)/4
:= 4 × (44 − 4) − 4 − 4
:= 5 + (55 − 5/5)/(5 − 5/5)
:= 5 × (5 + 5) × (5 × 5 − 5)
:= 66 × (6 + 6) − 6
:= ((66 − 6)/6)(6×6/(6+6))
:= 777 + 7 + (7 + 7)/7
:= (7 + 7 + 7 − 7/7) × (7 × 7 + 7/7)
:= 8 × (88 + 8) + 8 + (88 − 8)/8
:= 888 + 88 + 8 + 8 + 8
:= 9 × 99 − 99 − 9 + (9 + 9 + 9)/9
:= 999 + 9/9.

Values are calculated up to 1.000.000 (.txt file), but the work is written only from 0 to 1000. For details, refer Taneja
[8]. Recent extension to 20000 in four parts refer Taneja [9, 10, 11]
1.4 Forth Way: Single Letter Representations
We observe that the numbers written in previous section 1.3 are in terms of each digit, not necessarily symmetric. But
there are numbers, that can be written in a symmetric way, see examples below:
5=
11 − 1 22 − 2 33 − 3 44 − 4 55 − 5 66 − 6 77 − 7 88 − 8 99 − 9

Motivated by this idea, instead working for each digit separately, we can work with a single letter "a", for example,
• Running-Type
5 := (aa − a)/(a + a)
1991 := (aaaaaa/aaa × (a + a) − aa)/a
6 := (aa + a)/(a + a)
2020 := (aaaaa − a)/aa × (a + a)/a
55 := (aaa − a)/(a + a)
2035 := (aaaa − a)/(a + a + a) × aa/(a + a)
56 := (aaa + a)/(a + a)
4477 := (aaa/(a + a + a) × aa × aa)/(a × a)
561 := (aaaa + aa)/(a + a)
4999 := (aaaaa − aaaa − a − a)/(a + a)
666 := aaa × (aa + a)/((a + a) × a)
5000 := (aaaaa − aaaa)/(a + a).
925 := (aaaaa − aa)/(aa + a)
1089 := (aaaa − aa − aa)/a
• Fraction-Type
aa − a
a+a
aa + a
6 :=
a+a
aaa − a
55 :=
a+a
aaa + a
56 :=
a+a
aaaa + aa
561 :=
a+a
aaa × (aa + a)
666 :=
(a + a) × a
(aa + a) × aa
− a) × (aa + a)
a
786 :=
(a + a) × a
aaaaa − aa
925 :=
aa + a
aaaa − aa − aa
1089 :=
a
aaaaaa
× (a + a) − aa
aaa
1991 :=

The full work is from 1 to 11111 numbers, written in two different ways. One running type [15] and another in
fraction-type way [16]. For previous work refer [12, 13]. The summary of author’s work on recreation of numbers in
different situations refer [22].
1.5 Running Expressions
Previous subsections, works with natural numbers in different situations using 9 or 10 digits. In this section also we shall
do similar kind of work, but in little different way. It is based on the idea of subsection 1.1. We divide the numbers in
equal parts, two or three in such a way that the results are increasing and decreasing orders 1 to 9 or 9 to 1 or 9 to 0
separated by equalities, for example,
1234 = (5 + 67)/(8 × 9)
98/7 + 6 = 54/3 + 2 × 1.
Below are more examples, written in increasing and decreasing ways:
• Increasing Order
12 = 3 + 4 + (5 × 6 + 7 + 8)/9
123 = 4 + 5 + 6 × 7 + 8 × 9
1234 = −5 + 6! + 7 + 8

Above examples give representations separated by equality sign having the digits in either increasing and/or decreasing orders. There are numbers that can be written in increasing as well as decreasing orders at the same time with single
or double equality signs, such as

The above three examples divide the numbers in two and three parts respectively with equality signs using the numbers in increasing as well as decreasing orders. From the examples (1), (2) and (3), we observe that the operations used
are addition, subtraction, multiplication, division, potentiation, factorial and square-root. More details can be seen
in [22, 18, 19]. In this work, our interest is to found examples similar to (1), (2) and (3), using Fibonacci sequence values.
1.5.1 Running Expressions with Fibonacci Sequence
Fibonacci sequence numbers are well known in literature. This sequence is defined as
F (0) = 0,
F (1) = 1,
F (n + 1) = F (n) + F (n − 1),
n ≥ 1.
Similar to (1) and (2), given above, below are examples of running expressions using Fibonacci sequence numbers.
Most of the results uses basic operations, except numbers 21 and 9876, where extra operation, such as factorial is used.

1.5.2 Running Expressions with Triangular Numbers
Triangular numbers are very much famous in the literature of mathematics. These are given by
1, 3, 6, 10, 15, 21, ...
The general formula to write these numbers is given by
T (n) = 1 + 2 + 3 + ... =
n +1
= C (n + 1, 2)
2
The letter "C " represents as "binomial coefficient".
In this paper our aim is to bring running expressions by use of triangle numbers. This we have done in subsequent
sections. Due to high quantity of numbers, we the work is limited to 3 digits in case of single equality. As a part of results,
see below some interesting examples,

2 Single Digit Representations From 1 to 20000
The whole work brings numbers 1 to 10000 written in terms of single digits. Since, it is not possible to put all the numbers
in single work, we divided it in four parts as given below:
• Part I : From 0001 to 5000;
• Part II : From 5001 to 10000 [9];
• Part III : From 10001 to 15000 [10];
• Part IV : From 15000 to 20000 [11].

This paper brings first part giving single digit representations of natural numbers from 1 to 5000. For other parts
refer [9, 10, 11].
Remark 2.1. Due to high quantity of numbers the there so many extra brackets. After simplifications, these unnecessary
brackets can be removed easily.
2.1 Single Digit Representation: 1-5000
This subsection bring the first part of the whole project. Here, the numbers are represented from 1 to 5000 in terms of
different digits. The work done previously up to 1000 [6] is also repeated here.
