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!
