Warm Up: September 18th, 8th Grade

Order matters.  Sometimes it seems like it is chaotic, but if you don't follow the order, it won't turn out correctly.  Math is the same way.  This is why I can get two or more answers that have their calculations right and still be wrong.  So if you don't follow PEMDAS, you're going to get wrong answers and be unhappy about it.

1.  3 * (2-5) + 4 - (-3)

2. (4*6) + (-2*12)/3 - 12

3. (10/4) * (16/8)^2
