remember the order of operations. for this particular problem, division and multiplication come first. since they are both present in the problem, and neither one is supposed to be performed before or after the other in the order of operations, you should start from left to right, the same way you read.
times the 80 and the 2 together, and then divide it by 5.
now do the addition and subtraction. again, neither subtraction nor addidtion is supposed to be performed before or after each other in the order of operations, so you start from the left to the right.
simply complete the steps.

you have to use the order of operations to get this answer. so first you would do your multiplication and division: 80 x 2 = 160
160/5 = 32. Then you would add 10. 32 + 10 = 42. then subtract 7. 42-7 = 35.

160/5 + 10 - 7
32 +10 - 7
42 - 7
35
Get a calculator. You have one on your computer.
