### Pi To 10,000 Decimal Places

Perhaps because we have ten fingers, we use a decimal system based on powers of 10. Therefore, multiplying and dividing by powers of 10 is easy. For that we just need to move the decimal point.

6 Multiply by Powers of 10 To multiply a number by a power of 10, such as 10, 100 or 1000, we need to move the decimal point to the right of the correct number of places. To multiply by 10 we move one place to multiply by 100 we move two places to multiply by 1000 we move three places and so on.

Using the same examples as on the previous slide, we can use exponents to multiply by powers of 10 1.25 x (move the decimal once to the right) 1.25 x (move the decimal to the right twice) 1.25 x (move the decimal to the right). three times) 1.25 x (move the decimal to the right six times) ** The exponent is the decimal Indicates how many times to move the point to the right 1 2 3 6

11 10 Dividing by divisible powers is just as easy; The decimal is moved to the left instead of to the right. 250.6 ÷ 10 = 25.06 250.6 ÷ 100 = 2.506 250.6 ÷ 10 = 250.6 ÷ 10 = 4 6
