Question

Add without using number line:

$(-252)+(-45)$

Answer 1

$(-252)+(-45)$

Here, $-252$ and $-45$ are both negative.

For adding integers with the same sign, we have to add their absolute values and the sum obtained will have a negative sign if both integers are negative.

Therefore, $(-252)+(-45)$$=-(\left|-252\right|+\left|-45\right|)$

$=-(252+45)$

$=-297$.

Final Answer: $(-252)+(-45)$$=-297$.
