Math CentralQuandaries & Queries


Question from mark, a parent:

How many three number combinations can I get using 1,2,3,4,5? I can use a number more than once.


Try a simpler version of the same problem: list all the two number combinations with 1,2,3. Remember that you can use a number more than once.

Now list all the three number combinations with 1,2.

See the pattern?

Good Hunting!
