Multiplying Multiples of Ten

Multiply These Numbers

100 x 2 =

200

1,000 x 3 =

3,000

10,000 x 7 =

70,000

100,000 x 9 =

900,000

Multiplying Multiples of Ten

Did you notice that all you

have to do is multiply 1 x whole

number & add the zeros behind?

100 x 2 =

200

1,000 x 3 =

3,000

10,000 x 7 =

70,000

100,000 x 9 =

900,000
