Question

Add without using number line:

$(-381)+(-229)$

Answer 1

Given that, $(-381)+(-229)$

Here, $-381$ and $-229$ 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, $(-381)+(-229)$$=-(\left|-381\right|+\left|-229\right|)$

$=-(381+229)$

$=-610$.

Final Answer: $(-381)+(-229)$$=-610$.
