a:Start at 4 on the number line and move 3 to the left.
b:Start at 4 on the number line and move 3 to the right.
c:Start at -3 on the number line and move 4 to the left
d:Start at - 3 on the number line and move 4 to the right.

Answer 1

The answer to your problem is, B. Start at 4 on the number line and move 3 to the right.

Explanation:

On a number line, the positive numbers are to the right of zero and the negative numbers are to the left of zero.

Well According to the question:

4 -(-3)

This expression is starting from + 4 and it will move to the direction of positive 3 which is right side from the 4.

Remember:

Its a mathematic rule for order of operations that tells us the correct sequence of steps. We can remember the order using PEDMAS rule ( from left to right)

Thats why we will start from 4 nor 3 and will move on the direction of +3.

Thus the answer to your problem is, B. Start at 4 on the number line and move 3 to the right.
