What is the sum of all the positive two-digit integers where one of the digits is four times the other?

__if the first digit is 1, then the second digit is 4 times that: 4.so 14 and 41. in both cases, one digit is 4 times the other.if the first digit is 2, then the second digit is 4 times that: 8so 28 and 82if the first digit is 3, then 3 * 4 = 12, which would not be a valid digit. in fact, 1 and 2 are all the digits that you could multiply by 4 to still get a valid number.14 + 41 + 28 + 82 = 165

Value is 6 i think k
