Question

Find the solution of following addition using number line: (+4) + (-3).

Answer 1

First we move 4 steps right to the integer 0 to reach the integer (+4). Now from this point move 3 steps to the left of the integer +4 (as we need to add -3 to +4) on the number line.

Thus (+4) + (-3) = 4 - 3 = 1
