Use your understanding of order of operations (BEDMAS) to solve the following problems.
a.
1 + (15 – 8)
=1+7
=8
b. 8 ÷ (5 + 3)
=8÷8
=1
c.
32 ÷ 4 + 8
=8+8
= 16
d. (2 + 8) ÷ 2 x 5
= 10 ÷ 2 x 5
=5x5
= 25
e. (8 x 2) – (12 – 1)
= 16 – (12 – 1)
= 16 – 11
=5
f.
(5 + 1 + 4) ÷ 10
= (6 + 4) ÷ 10
= 10 ÷ 10
=1
g.
9x3–3x3
= 27 – 3 x 3
= 27 – 9
= 18
h. (6 – 4) x (4 x 2 + 2)
= (6 – 4) x (8 + 2)
= 2 x (8 + 2)
= 2 X 10
= 20
Fill in one pair of brackets to make the following equations true:
a.
b.
(3 + 6) x 3 = 27
10 – (2 + 7) = 1
