You can,
if you have a square with side 5
you can multiply 5*5=25
or you can add 5+5+5+5+5=25
If you want to do this just take one of the numbers and add it to itself the other numbers times.
so if you have 7*8
you add 7 to itself 8 times, so add 8 7's
7+7+7+7+7+7+7+7=56
or add 7 8's
8+8+8+8+8+8+8=56
Multiplying is much easier.
