29.75 and 257.9
It is rounding a decimal representation of a number so that there are two digits after the decimal point.
The answer depends on how many decimal places are in the summands.
You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
To the left of the decimal point, you place a decimal at an interval of every three digits.
Three. This refers to the number of significant digits AFTER the decimal point.

Well, darling, the number 36.4375 has four decimal places. It's not rocket science, honey, just count those digits after the decimal point. So, in this case, you've got 4 decimal places to work with. Hope that clears things up for you!

Pi to 144 decimal places is written thus: 3.14159265358979323846264338327950288419716939937510 58209749445923078164062862089986280348253421170679 82148086513282306647093844609550582231725359 The sum of these first 144 decimal digits (after the decimal point) is 666.
There is no need to round 1097 to any decimal places as there are no digits following a decimal point.
You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
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.
To the left of the decimal point, you place a decimal at an interval of every three digits.
3.1415926535897932384626433832795 (that's 31 decimal places) !
Three. This refers to the number of significant digits AFTER the decimal point.
The number of digits on both sides of the decimal point is up to you! For instance, Pi is accepted as being 3.14 (two places) for general use. But, 3.14159265359 is to 11 places, and it can stretch on into infinity!
