I am having problems with my math homework. Here are the problems:
1. Comare 27-6+7 and 27-(6+7).
2. Add parentheses to make this true. 15-6-3=12
3. Add parentheses and brackets to make this true. 3x100/20+5=20
-Thanks!

1. 27-6+7 and 27-(6+7)
27- 6 + 7 = 21 + 7 = 28
27 - ( 6 + 7) = 27 - 13 = 14
2. 15-6-3=12
15 - ( 6 -3) =
15 - 3 = 12
3. 3x100/20+5=20
3 x (100/20) + 5 =
3 x (5) + 5 =
15 + 5
20
Thanks! Are you a boy?
