Answer 18

Okay, I got most of it done. Can you help me with 29 A?

Answer 19

I put parentheses everywhere but I can't seem to get the answer 10...

Answer 20

@Amistre64?

Answer 21

29A working on it ...

720/2 = 360, so adding to it an multiply it out is just making it bigger

720/9 = 80, and multiply it just gets bigger

720/(a+b*c) seems to be our best route

if a+b*x = 72 we got it made right?

Answer 22

a+b*c that is

Answer 23

9*8 = 72

(2+7) * 8 = 72

720/((a+b)*c) seems fair

Answer 24

Okay, \[720\div[(2+7)\times2^{3}]\]

Answer 25

thatll do 10 yes

Okay, almost done.
