Answer 2

Answer : The correct option is, (B) -7 + 12 = 5

Step-by-step explanation:

Number line : It is a representation of numbers on a line in which negative numbers are written on left hand side of the zero and the positive numbers  are written on right hand side of the zero.

On moving right, the number increases and on moving left, the number decreases.

For example : 1 is greater than -3, -2 is greater than -5, etc.

First we are moving on left side that means from 0 to -7 and then we are moving to right side that means from -7 to 5 which add upto 12.

According to the given figure we conclude that,

$-7+12=5$

Hence, the correct option is, (B) -7 + 12 = 5
