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...
