+2863 4+5-7*9/3
I tried PEMDAS, but I'm not sure.
Honestly, this is supposed to be a problem for 3rd graders, and I feel ashamed to have difficulty on this.
+1443 4+5-7*9/3
first according to pemdas you multiply, so you will have-
4+5-21
now all that's left is addition and subtraction, so go in order, which ever comes first. Next, 4+5 which will give us-
9-21
now just subtract and you get
-12
