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
