Question

Find -63 + ( - 198) + ( - 11).

Answer 1

-272

Explanation:

We have the following operation:

`\: -63\: +\: \mleft(\: -\: 198\mright)\: +\: \mleft(\: -\: 11\mright)`

As they are all of the same (negative) sign, they are added and the negative sign is put, just like this:

`\: -63\: \: \: -\: 198\: \: -\: 11=-261-11=-272`
