Question

Answer 1

(a)
`-4+9`

(b)
`-2 * 3`

Explanation:

Part A

Moving 4 steps left, then moving 9 steps right

When you move left, we indicate with a negative sign while a move right is indicated with a positive sign.

Moving 4 steps left = -4

Moving 9 steps right = +9

Therefore, an expression for the statement is:
`-4+9`

Part B

When you lose or owe in word problems, it is usually indicated using a negative sign.

Therefore, the statement Shari lost 2 pencils can be represented with the integer: -2

Since Shari lost 2 pencils on 3 occasions, we simply have:

`-2 * 3`
