Math Story A Lazy Mathematician and Multiplication
Did you learn how to skip-count? Let’s count the stars in
the sky!
3+3 +3 +3+3 +
Counting the stars like that will take you forever! No!
You might want to try, but if you were me, you would use
multiplication instead.
Count the stars like this:
3+3+3+3+3+3+3+3+3=9^3
5+5+5= ^5
2+2+2+2= ^
3+3+3+3+3= ^
4+4+4= ^
