Dr. Math,

How do you do a hard multiplication problem like 14x7?

Dear Alice,

In such a situation I would break this hard problem up into two
easier problems.  Since 14 sevens is the same as 10 sevens plus
4 more sevens, it makes sense to do those two problems first, and
then add up those two answers to get the grand total answer :

How much is 10 sevens ?  ................  70
How much is  4 sevens ?  ................  28
----
Add them up to find 14 sevens  ..........  98

I hope this helps.  When your class gets to learning about ways
to do multiplication of these larger numbers, be sure to remember
that the 1 in 14 really means "ten".  That's important to know.
