My son is in 4th grade, gifted/talented class.
He's working on math "sentences" and specifically figuring out where to put parenthesis to make the sentence true. I know how to do this, and have helped with all the problems except for this one, and I just can't figure it out.
I've tried several trains of thought, but simply can't figure out where the parenthesis should go to make the following mathematical statement true.
Am I missing something?
6 - 5 x 5 / 7 + 5 = -22 4/7
