In base ten, there are 9000 four digit number, the numbers are from 1000 to 9999. If you allow leading zeros, then there are 10000 numbers. [0000 - 9999]
9999 = 9999 It does NOT equal '1' 1 = 1 9999 ~ 10,000 (ten thousand)
If by "between" you mean "between but not including", then the answer is 9999 - 999 - 1 = 8999.If on the other hand, you mean to include both 9999 and 999, then the answer is 9999 - 999 + 1 = 9001.
5 zeros
15 zeros
If leading zeros are allowed, then there are ten thousand possible: 0000 through 9999. If leading zeros are not allowed, then it is 1000 through 9999, eliminating 0000-0999, and now there are nine thousand possibilities.
41duodecillion is a 1 followed by 39 zeros
Since you can add zeros to the right end of a decimal expression, .888 is the same as .8880 Now, which is smaller, .8880 or .9999? .888 is right. ■
