How do you solve -13 + (-56) ÷ 14 + 9? I googled the answer which said -8. But I don't know how to get the answer

Order of operations is a strict set of rules that dictate how to evaluate any expression. I have laid the order of operations out for you:
 

1. Simplify within grouping symbols such as parentheses or brackets from left to right.

2. Simplify exponents from left to right.

3. Perform multiplication or division, whichever operation comes first from left to right.

4. Perform addition or subtraction, whichever operation comes first from left to right.

 

If something is higher on the list, then it has greater priority. Let's apply this knowledge to this particular problem:

 

\(-13+\textcolor{red}{(-56)\div 14}+9\) Notice how division has the highest priority in this particular expression.
\(\textcolor{red}{-13-4}+9\) Since there is only addition and subtraction remaining, perform the operations from left to right.
\(\textcolor{red}{-17+9}\) Simplify.
\(-8\)
