Square Numbers

We discussed what square numbers are in What's So Special? Remember these are numbers that are multiplied by themselves.

We can square any number.

Examples

$$122=12×12 $$= $$144

$$1002=100×100 $$= $$10000

 

Cube numbers

Cube numbers are numbers that are multiplied by themselves two more times. (that number three times in total)

Examples

$$23=2×2×2 $$= $$8

$$53=5×5×5 $$= $$125
