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.
$$122=12×12 $$= $$144
$$1002=100×100 $$= $$10000
Cube numbers are numbers that are multiplied by themselves two more times. (that number three times in total)
$$23=2×2×2 $$= $$8
$$53=5×5×5 $$= $$125
Evaluate $$82+7
Evaluate $$122−92
Evaluate $$53+32
