What is a 1 digit multiplication problem?
A one digit multiplication problem is one in which the numerals
being multiplied have only one digit. Examples would include: 6x2
or 5x3 or 7x4 or 1x8. (These are just a few examples. The list of
all the possible one digit multiplication problems would be very
long.)
A two digit multiplication problem is one in which the numbers
being multiplied have two digits. Examples would include: 12x43 or
16x21 or 75x23.
