May you post the question in the comments so i can work it out for you
I think the answer is 90?
Answer to a : 30-19=x but for b i’m not that smart
Answer:
no
Step-by-step explanation:
-1 - (-12)
the two negative signs before the 12 cancel out so it ends up being
-1+12
-1+12=11
11 and -1 are not equal to each other
