If x = 6, y = –2, and z = 3, what is the value of the following expression?
xz + xy/z2
2/3 = is the answer (it tells me)
But what I don't get is this:
(6)3 + (6)-2/9
18 + - 12/9
Now wouldn't it make sense to keep 12/9 because of order of operation and then add -12/9 to 18?
I don't get why it's (18 - 12) / 9 because Order of Operation says divide first then add.
Can someone tell me if there's like an exception to the OOO rule please.
