Notes and Strategies to Make Math Simple
1 x 100 =100
2 x 100 =200.
II am sure you can multiply harder ones.
24 x 1000
If you think it is 24,000 you are correct.
Now watch what happens when you start
with a decimal not at the end but somewhere else, like in the middle
13.56 x 100 = 1356. Multiplying by 100 simply means to increase the value of a number by moving the decimal two places to the right.
So if multiplying moves the decimal to the
right, division will move it to____________
Try some easy ones.
34 divided by 10 =3.4
34 divided by 100 = 0.34
34 divided by 1000 =0.034
Notice as soon as there are no ones you indicate that with a 0.

Oh , By the way, you just did metric work!
Multiplying or dividing by 10's 100's or 1000's is a matter of finding out where the decimal point needs to go. All numbers have a decimal point. You know this when you number your paper.......
Now multiply by 10 and watch what happens:
