Well, isn't that just a happy little question! When you add tens to a number, the tens digit increases by one while the ones digit stays the same. It's like adding a little touch of sunshine to your number, making it just a bit bigger and brighter. Just remember to keep those digits happy and balanced as you add those tens!

2 tens and 13 ones add up to 33 because 10 +10 +13 = 33.
The answer is 43 and the reason why the tens digit changes is because 7 + anything over 2 will change the digit. If just added 7 + 6 it would be 13 then add 30. 1 + any whole number over 8 will change the tens digit 2 + any whole number over 7 will change the tens digit 3 + any whole number over 6 will change the tens digit 4 + any whole number over 5 will change the tens digit 5 + any whole number over 4 will change the tens digit 6 + any whole number over 3 will change the tens digit 7 + any whole number over 2 will change the tens digit 8 + any whole number over 1 will change the tens digit 9+ any whole number over 0 will change the tens digit ect

Well, honey, to get from 212 to 572, you need to add 360. And since each ten is worth 10, you gotta add 36 tens. So, there you have it, add 36 tens to 212 ones and 100 to get to 572.
72 is not a prime number
The answer would be 37.
The answer depends on what the tens digit is greater than, and what the ones digit does then.

To convert tens and units into a single number, you can simply multiply the tens digit by 10 and then add the units digit. This will give you the combined value of the tens and units as a single number.
It increases by 1 unless it was a 9. In that case, it becomes a 0 and the previous digit (to the left) increases by 1. Unless that was a 9 in which case ... and so on.

When you multiply a two digit number by another, you use the distributive property because you basically are taking the tens digits times both the other tens digit and the ones digit, then the ones digit times both the other tens and other ones digits. That sounds confusing, I know, but I'll explain. If you're taking 12 times 25, you are basically doing the problem (10+2) x (20+5). You take ten times twenty, then ten times five, then two times twenty, then two times five, and add them all together.
Add the last digit (units digit) to twice the previous digit (tens digit). If this sum is divisible by 4, so is the original number.
