Using power-of-notation makes it easy to multiply numbers.

You multiply the number together - using a calculator if needed.

Basically, it means to add the numbers in your head.

its makes it easier because its been seprated by each properties

you can't multiply on LMC you can only add numbers so you have to add the same number as many times as you need to multiply example 5 times 3 5+5+5

25 x 3 = 96
