You do by subtracting one from the previous number and adding 10 to the top number of the digits you are regrouping. Subtract those two digits and you should get your answer.

Count the number of digits after the decimal point in the first number being multiplied. Count the number of digits after the decimal point in the second number being multiplied. Add the two numbers. This is the number of digits after the decimal point in the answer. But make sure that any trailing 0s are included. To calulate 0.42 * 3.451: 41*3451 = 144942 Digits after point in first number = 2 Digits after point in second number = 3 2 + 3 = 5 So digits after point in answer = 5 So answer = 1.44942 But To calulate 0.42 * 3.45: 42*345 = 14490 <<< it is vital that the last 0 here is kept till the last stage. Digits after point in first number = 2 Digits after point in second number = 2 2 + 2 = 4 So digits after point in answer = 4 So answer = 1.4490 = 1.449

There should be 125 combinations, but if you can only use the numbers once for each 3 digit number, then it should be 120. It's 125 because if the digits could be used more than once for each number then its the number on possible numbers (so there's 5 in this case, 2, 3, 5, 8, and 9) to the power of how big the digit is (in this case it's 3) It's 120 because if the digits could only be used once in each number then the combinations would be the number of possible numbers (again, 5) factorial, so 5!

There are 70,674 3's in the first million digits of pi. * * * * * There are 100,230 3s and 100,106 9s. Since the decimal representation of pi is essentially random, the number of times any digit appears should be approximately 10% of the total number of digits. So, for a million digits, there should be around 100,000 of any digit so it should have been immediately apparent that the previous answer was extremely unlikely. In fact it was incorrect to a very large degree!
