Ok so first you do left to right

So, let’s take care of ( 123+42+7) which would give you

172.
Then, we would take care of (33-122-10) will give you a negative number of 99 if that is not correct then you will have to switch 33 and 122 which will give you a positive 99.

Then add 172+99 which will give you your sum of 271

(123 + 42 + 7) + (33 − 122 − 10)
= 172 + (- 99)
= 172 + 99
