Question

Which expression is represented on the number line?

1) (-12) ÷ (-3)
2) -3 ⋅ -4
3) 0 - (-12)
4) 3(-4)

Answer 1

To solve the expression represented on the number line, we need to subtract -12 from 0.

Step-by-step explanation:

The expression represented on the number line is 3) 0 - (-12). To solve this expression, we need to follow the rules of subtraction:

1. Change the sign of the subtracted number (-12) to become +12.
2. Subtract the smaller number (+12) from the larger number (0).
3. The answer takes the sign of the larger number, so the expression becomes 0 + 12 = 12.

Therefore, the expression represented on the number line is 12.
