Use the rules for multiplication by powers of 10 to calculate 3 × 100
padilas [110]
3 × 100 = 300

the easiest way to do it is just add the same amount of zero's to the number you multiplied with. for example

3 × 10000 if you would just take out the zero's
it would look like this. 3 × 1

the answer of course would be 3 then you can put the zero's back in the answer (30000)

at least that's how I understood it

3 × 100 =

3 × 1(00) =
-->

-->
(00)
3 × 1(00) = 3

3 × 100 = 300
