Let's denote the tens digit as x and the ones digit as y. According to the given conditions, we have the following equations:
A) If a number has two digits, then the sum of its digits is less than the value of the original two-digit number.
The only prime number less than 3 is 2.

In the context of decimal numbers, comparing 2.35 and 2.53 involves looking at the digits after the decimal point. The number 2.53 is greater than 2.35 because the digit in the tenths place (3) is greater than the digit in the tenths place of 2.35 (5 vs. 3). Therefore, 2.53 is greater than 2.35.
A) If a number has two digits, then the sum of its digits is less than the value of the original two-digit number.
No, a 4-digit number is not always less than a 5-digit number. The value of a number is determined by the digits it contains, not the number of digits. For example, the 4-digit number 9999 is greater than the 5-digit number 1000. It is important to consider the actual numerical value when comparing numbers, not just the number of digits.
91 since the ones digit is 8 less than 9 and the two digits, 9+1 = 10, a two-digit number.
The only prime number less than 3 is 2.

To round any number, look at the digit to the right of the place you are rounding to. If the digit is 5 or more, change the digit in the place you are rounding to to the next higher digit. If the digit to the right of the place you are rounding to is less than 5, leave the digit in the place you are rounding to as it is. Change all digits to the right of the place you rounded to to zeros. For example, 15.15 rounded to tenths is 15.20, or simply 15.2. 15.14 rounded to tenths is 15.10, or simply 15.1.

The number you are looking for is 50099. It is a five-digit number greater than 40000 but less than 70000. The ones digit (9) is greater than the ten thousand digit (5), all other digits (0) are the same, and the sum of the digits (5 + 0 + 0 + 9 + 9) equals 19.
102345 is the smallest [positive] 6-digit number with no repeats.
