Detailed Solution

Complete the sentence: 13 + -13 = 0
On the number line, when we move from right to left, the number decreases and from left to right, the number increases.
By marking points at equal distances, draw a number line.
Question ImageMove from 13 to 0 on the number line and count the steps.
On counting, we will have a count of 13 steps in a backward direction. Thus, we subtract 13 from 13 to get 0.
13−13=0
13+(−13)=0
Hence, -13 is the correct answer here.
