Best Answer

Because we have ten digits and have learned to count in tens. We use the numbers 0, 1, 2, ..., 9: that is ten different digits.

Q: Why is it a base 10 instead of base 9?

It is called the binary system. It uses only 2 numbers. The numbers are "0" and "1" This is a computer language. Base 10 is our regular number system... consisting of 10 numbers from 1-9 including 0

9 (base 10) = 1001 (base 2)

9 ≈ 10^0.9524 lg 9 ≈ 0.9524 (where lg is log to base 10).

9

Base 10 is based on groupings of 10, and the digits are called 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Base 11 is based on groupings of 11, and the digits are called 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and A. A is used instead of 10 to avoid confusion, because it is a single digit, not two digits that actually have the base 10 value of 11. Notice in 10 base 10, you are using 2 digits, a 1 in the tens place and a 0 in the ones place. In base 11, you only need 1 digits, an A, which has the same effective value.

9 (base 10) = 1001 (base 2)

1,2,3,4,10,11,12,13,14,20,21,22,23,24,30,31,32,33,34,40....It's just like counting in base 10 except when you get to a 4 (instead of 9) you carry over. There should never be a number over 4 in base 5.

9 ≈ 10^0.9524 lg 9 ≈ 0.9524 (where lg is log to base 10).

Intelligence and the ease of of using base 10 instead of base 12 or whatever.

01 02 03 04 05 06 07 10 (= 8 in base 10) 11 (= 9 in base 10) 12 (= 10 in base 10)

You will have to mention what base 1002 is in because it could be any base from 3 to 9.
