Understanding and memorizing the multiplication table is a necessary and important step for all young people when they are learning mathematics. In this lecture we give a few small tricks or lessons that can help. These deal with multiplying by ten, the important distinction between even and odd, and multiplying by five, three and nine.

Then we give some typical sample problems involving multiplication, including some word problems. Of course the student ought to do many more such exercises!
