Let's say the number is 57.
You take the first digit, 5, and add a zero to the end of it.
So you have 50.
Then you take the second digit, 7, which stays the same.
Therefore you have fifty (50) - seven (7).
The greatest sum of two two-digit numbers occurs when you add the largest two-digit numbers together. The largest two-digit number is 99. Therefore, the greatest sum of two two-digit numbers is 99 + 99, which equals 198.
There are 21 two-digit prime numbers.
The only two numbers that represent a binary digit are 0 and 1
7 two-digit numbers.

The product of two 2-digit numbers cannot be a two-digit number because the smallest two-digit number is 10, and the smallest product of two 2-digit numbers (10 × 10) is 100. Since 100 is a three-digit number, any multiplication of two 2-digit numbers will yield a product that is at least 100 or more. Therefore, the product must always be three digits or greater.
