The number of 3-digit numbers with no repeated digits is simply 10x9x8 = 720, if you allow, for example, 012 as a 3-digit number. There are 10 digits, any of which might be the first digit. The second digit can be any digit except the digit that was used for the first digit, leaving 9 possibilities. The third digit then has 8 possibilities, since it can't be the same as the first or second digit. The actual number of possible area codes will be lower, because there are additional restrictions on the number combinations for a valid area code. For example, in North America (USA, Canada, etc.), the first digit of an area code cannot be 0 or 1 and the middle digit cannot be 9.

No. It depends on how good you are at arithmetic.
You need to regroup when you add the numbers together and they add up to a number that is ten or more. For example: 1 164 +518 _____ 682 If it is over ten, take the first digit of the number and put it above the next number. Then, add that number onto the sum of the other digits underneath it.
