Solve (Easy)
15 + 3 - 2 x 7 =
4
(-4)² - 1² =
15
10^3 = 30
10 x 10 x 10 = 1000
Multiplied 10 x 3
(41 - 4) x 5 =
185
(52 – 6) + 11²
167

1
The order in which two numbers are added or multiplied does not change their sum or product (e.g., 2 + 3 = 3 +2 or 4 x 7 = 7 x 4). Associative, Identity, or Commutative?
Commutative property
80 / 2 - (4 - 1)^3 = 31
= 13
Multiplied 3 x 3 instead of 3 x 3 x 3.
(4-2)^3 / 2 - 4
0
12 + 6² ÷ (1 + 4 x 2) - 3 x 2² =
4
This property for addition tells us that zero added to any number is the number itself.
Identity Property
2^3 - 16 + 2^3 / 6 = -3
= 4
Multiplied 2 x 3 and 18 x 3
