Question

On the number line, if integers $A$ and $B$ are at equal distance from 0, then the value of $A+B$ is

• A. 0
• B. 2
• C. -2

Answer 1

The correct option is A 0

Given that $A$ and $B$ are at equal distance from $0$ on the number line, meaning integer $A$ is opposite or mirror reflection of integer $B$.
Since $A$ is at left to 0 and $B$ is at right to 0, $B$ is a positive integer and $A$ is negative of $B$.
$\therefore$ B+ (-A) or (-A) + B = 0
