I need help on this problem:
8+9-10
I just don't understand if you do that 8+9 part first or the 9-10 part first
Can you just tell me the steps to it? Thanks!

It doesn't matter.

8+9-10=17-10=7 or
8+9-10=8-1=7

Does it make a difference?
<b>8+9-10 = </b>

8 + 9 = 17
17 - 10 = 7

Or --
9 - 10 = -1
8 - 1 = 7
