Question

Add without using a number line.

$\left(8\right)+\left(-2\right)$

Answer 1

Here, $\left(8\right)$ and $\left(-2\right)$are of opposite signs.

Therefore, we find differences between absolute values.

$=\left(8\right)+\left(-2\right)$

$=8-2$ ( Rule: Multiplication of + and - is - )

$=6$
