Write an integer to describe the situation:

The Dead Sea is 1,312 feet below sea level.

-1,312

Write an integer to describe the situation:

A helicopter rises 75 feet.

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
