Multiplication is a shortcut for addition.
When you add, you combine amounts.
When you have equal amounts to add, you can multiply to find the total.

2 2 2 2 2+ + ++
2 + 2 + 2 + 2 + 2 = 10

I can also multiply
2 by 5
to find the total.
2 is the number oftires on each bike.
5 is the numberof bikes.
2x5=10 Total number of tires

is the operation of making equal groups and finding the number in each group
or the number of groups.
Wow!!!!!!! That sounds cool!
