... B there is at least one occurrence of each of 1, 2 and 3; C it is not divisible by 2, and so the final digit is either 1 or 3; D it is not divisible by 3, and so the sum of its digits is not divisible by 3. The largest and smallest five-digit integers that satisfy both condition A and condition B ar ...

Elementary arithmetic
Elementary arithmetic is the simplified portion of arithmetic that includes the operations of addition, subtraction, multiplication, and division. It should not be confused with elementary function arithmetic.Elementary arithmetic starts with the natural numbers and the written symbols (digits) that represent them. The process for combining a pair of these numbers with the four basic operations traditionally relies on memorized results for small values of numbers, including the contents of a multiplication table to assist with multiplication and division.Elementary arithmetic also includes fractions and negative numbers, which can be represented on a number line.
