WILL BE MARKED AS BRAINLIEST !!! <br> Solve<br> (−22 −4 + 8)+ (52 + 2 − 25)
anygoal [31]

Answer:

11

Step-by-step explanation:

1) lets get rid of the parentheses, we dont really need them:

−22 −4 + 8+ 52 + 2 − 25

Following order of operations we need to work from left to right

so

-22-4=-26

-26+8=-18

-18+52=34

34+2=36

36-25=11

the answer is 11

hope this helps
