75 or +75
What is the sum of two opposite integers?
ZERO
Which is greater -45 or -42?
-42
Order 0, 41, 3, -20, -10, and 10 from greatest to least.
41, 10, 3, 0, -10, -20
Find the sum.-11 + -18
-29
Find the difference.-12 - 12
Use Leave, Change, Opposite:-12 – 12
-12 + (-12) = -24
What is -3 plus -6 plus 4?
-3 + -6 + 4-9 + 4 = -5
Solve.3 + (-6) – (-3)
3 + (-6) – (-3)-3 – (-3)
Using Leave, Change, Opposite: -3 + 3 = 0
Find the value of x – y if x = 9 and y = -16.
9 – (-16)9 + 16 = 25
Find the product of -4 and -8.
-4 x -8 = 32
Find the quotient of 45 and -9.
45 ÷ (-9) = -5
