A googol is one followed by 100 zeros ( 100 digits). That is less than a billion digits, for sure.
But a googolplex is one follwed by a googol number of zeros. That is more than a billion digits, for sure.
The digits of pi are known to more than a trillion (1012) digits, but it is impossible to state all of them in this forum.
The number system we commonly used, known as the decimal system, has 10 digits (0 to 9). It is possible to use other number systems, with a different number of digits. Any numbering system based on the same principle (the principle of place-value) must use 2 or more digits.
The least whole number with 6 digits is greater because it has more digits than 5 digits.
In a measurement the digits that are an approximation are only those in proper scientific notation. The more digits that are added to the number the more the number becomes exact.
It is greater because with more digits the greater the value of the number will be.
answer
Different countries have different number of digits. You need to be more specific.
The sum of your digits is the total number arrived at after adding two or more numbers.
a is a number with one or more digits to the right of a decimal point.
No.

It's the number that has more digits to the left of the decimal point (if there is no decimal point, it's the number with more digits). If the number of digits to the left of the decimal point is the same, find the position farthest to the left where the digits are different. The number with the greater of those two digits is the greater number. For example, 10000 is greater than 9999 because 10000 has more digits, and 6350 is greater than 6349 because the farthest-left position that is different is the tens place, and 5 is greater than 4.
