To multiply any number by 10, simply add a zero. Thus: 235 x 10 = 2350
To divide: 235 ÷ 10 = 23.5 put a decimal point one place to the left.
multiply centimeters by 10 to get millimeters since 1 cm = 10 mm
Multiply by 3. Then subtract 10.
1 Divide by 1000, multiply by 100
You are doubling whatever you are multiplying.
If you have an integer, add a zero at the end. For example, 5 x 10 = 50, 123 x 10 = 1230. More generally, to multiply by 10, you move the decimal point one position to the right. The decimal point can be implied; in the first example above, 5 is the same as 5.0, and 50 is the same as 50.0. However, this rule also allows you to easily multiply numbers with decimals by 10, for example, 2.24 x 10 = 22.4, or 1.5 x 10 = 15.

The first rule of math is to add, subtract, multiply, and divide.
To multiply by a positive power of ten, just add the number of zeroes as the number of the exponent. For example, if you have 103 which is 10 times 10 times 10, you will get 1,000. Hope this helps!
