What's the answer to this?
Yeah,
that's an easy one!
What if
we grouped the numbers... Put the
3
and the
4
in parenthesis? Remember the
Order of
Operations ...
In math, we always do what's in the parenthesis first!
So, if we do this, will we get the same thing?
Yep!
Now, what
if we group the numbers differently... Will we get
the same answer again?
Remember
that, if
both things equal
9,
then
those things have to equal each other!
