Answer 1

I'm not going to do all of them, but I'll help you get started.

 

Are you allowed to enter parenthesis to change the order, or does it have to go as is? For example, I could get

 

3 * (7 + 12) - 2 = (3 * 19) - 2 = 55,

 

but if I didn't use parenthesis, I would get

 

3 * 7 + 12 - 2 = 21 + 12 - 2 = 31.

 

Division was not mentioned in the problem, but I assume that's OK. You could do

 

(3 + 7) * (12 / 2) = 10 * 6 = 60
