Question

PLS HELP -8+13+(-13)!!!!

Answer 1

Hello..!

`\: \: \ \: \: \: \: \: \: \: \: \: \: \ \sf \red{ - 8 + 13 + ( - 13)}`

`\blue{\underline{ \green{ \underline{\sf \green{Explantation: }}}}}`

First, to solve the problem we take into account the Law of Signs:

`\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \green{\underline{ \blue{\underline{ \red{\sf Law \: of \: \: Signs:}}}}} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: - * + = -`

Once we have the law of signs, we will eliminate the parentheses to subtract, taking into account the law of signs

`\: \: \: \: \: \: \: \: \: \: \: \: \: \sf \green{ - 8 + 13 - 13}`

Then we must subtract knowing that when there is a minus and a plus it is automatically minus

`\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf \blue{- 5 - 13}`

Well, now we will subtract the only thing we have left, which in this case is 5 -13, which gives us -8

`\: \: \: \: \: \: \: \: \: \: \: \: \: \sf \: The \: \: result \: \: is \: \: from \\ \: \: \: \: \: \: \: \sf \green\longmapsto \pink{ - 8}`
