... 3. Suppose for some positive integers r and s, the digits of 2r is obtained by permuting the digits of 2s in decimal expansion. Prove that r = s. Solution: Suppose s ≤ r. If s < r then 2s < 2r . Since the number of digits in 2s and 2r are the same, we have 2r < 10 × 2s < 2s+4 . Thus we have 2s < 2r ...

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.
