When you multiply by ten to a power, move the decimal point to the right by the number of places of the power. 3.6 x 10 ^4 move decimal 4 places to right = 36000
Multiplying a real number by a positive power of ten moves the decimal point that number (the exponent) of places to the right. Multiplying by a negative power of ten moves it to the left. For example, the -3 power of 10 is 1/1000; multiplying by that moves the decimal point 3 places to the left.
The number of decimal places in a factor is determined by counting the digits to the right of the decimal point. In the case of the factor 40, there are no decimal places, as there is no decimal point present. Therefore, the number of decimal places in the factor 40 is 0.

One to one
Move the decimal point two places to the right and add a % sign.
Ignore the decimal point, multiply, count the places to the right of the decimal point, then count the same number from left to right in the answer,( after you add if nessicary) And put the decimal there. There's your answer. Example: 5 x 0.2 = 1.0 unusually, the number gets smaller after you add the decimal point.
