First check if it is divisible by 13. You need to delete the last digit from the number, then subtract 9 times the deleted digit from the remaining number. If what is left is divisible by 13, then so is the original number. For example. 195 The last digit is 5 so we delete that. Now 9x5=45 and we must subtract that from 195 So we have 19-45=-26 which is clearly divisible by 13. Now for 11 you need another test. Alternately add and subtract the digits from left to right. (You can think of the first digit as being 'added' to zero.) If the result (including 0) is divisible by 11, the number is also. Example: to see whether 365167484 is divisible by 11, start by subtracting: [0+]3-6+5-1+6-7+4-8+4 = 0; therefore 365167484 is divisible by 11. If your numbers passes both the divisibility tests, for 11 and 13, then it is divisible by both.
Since you need some math help, a one digit number is a number with one digit, such as 1, 2, 3, 4, etc. A two digit number is a number with two digits, such as 23, 71, 87, etc. And it seems that you need some grammar help, too. Your subject and verb do not agree; it should be "What are one and two digit numbers?". You're welcome... xD

On a number line, the digits from 10 to 99 are all two digit numbers. How many numeber are that? There is a short cut. You can subtract 10 from 99 and that gives you the number of numbers between 10 and 99 including 10, but you need to add one more to include 99 as well. So, 10 from 99 is 89 adding 1 is 90 ,which is the amount of numbers total that are two digit. The probability of guessing a two digit number is 1/90 =D
