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).

To find the two-digit counting numbers less than 30, we consider the numbers from 10 to 29, which gives us 20 two-digit numbers. The multiples of 20 that are two-digit numbers are 20. Since 20 is already included in the count of two-digit numbers less than 30, the total remains 20. Therefore, there are 20 two-digit counting numbers that are either less than 30 or a multiple of 20.
To multiply two digit numbers, multiply each place value of a factor by each place value digit and add the results.
