**Which is it?**

**Both answers can't be
right or we'd always be arguing about the
answers to math problems. The nice thing about
math is that there's always just ONE answer!**

**So, a long time ago,
math geeks decided to make a set of rules for what to do
first in a math problem.**

**These rules are called
"the order of operations."**

**I'll tell you what the
rules are in the next lessons... For now, remember
this word:**

**Go to the next lesson
to find out if the answer to our problem is
7 or
9!
And go all the way through to find out what all the
letters of
PEMDAS stand for!**
