My hundred digits are less than 10 digits and ones digits are greater than 10 digits, what's my number?

" .... and ones digits are greater than 10 digits"

makes no sense to me

assuming you meant "tens digit" then you might have

123
124
...
689
789

To find the number that meets the given conditions, you need to understand place values. The place values of digits in a number are determined by their position from right to left, with the rightmost digit being the ones place, the next digit to the left being the tens place, then the hundreds place, and so on.

In this case, you're looking for a number where the hundred digits are less than 10 and the ones digits are greater than 10. Let's break down the possible values for each place:

For the hundred digits:
- Since you mentioned that they are less than 10 digits, they can only be 0 to 9.

For the ones digits:
- Since you mentioned they are greater than 10 digits, they can be any value above 9.

To combine these conditions, you can have a number like 10X, where X represents any value above 9 for the ones digits, and the leading digit 1 represents the tens place.

Therefore, your number is in the form 10X, where X represents any number greater than 9.
