... • 20 Across. It is well known that a = 16 (in fact, it is the only integer expressible as both xy and y x for distinct x and y). For b, factor 1200 = 24 · 3 · 52 . A simple check gives you 39 = 24 + 10 + 5 = 25 + 8 + 6 = 20 + 15 + 4. Finally, since c cannot contain the digits 5, 8, 1, 6, 3, 9 (becau ...

... Let n be a k-digit integer in base b. Then n is said to be a Kaprekar number in base b if n2 has the following property: when you add the number formed by its right hand digits to that formed by its left hand digits, you get n. Or to put it algebraically, an integer n such that in a given base b has ...

... Exponents are shorthand for repeated multiplication of the same thing by itself. For instance, the shorthand for multiplying the number 5 three times is shown on the right-hand side of the "equals" sign in (5)(5)(5) = 53. The "exponent", being 3 in this example, stands for however many times the val ...

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.
