... 24. (E) Let R1, . . ., R5 and B3, . . ., B6 denote the numbers on the red and blue cards, respectively. Note that R4 and R5 divide evenly into only B4 and B5, respectively. Thus the stack must be R4, B4, . . ., B5, R5, or the reverse. Since R2 divides evenly into only B4 and B6, we must have R4, B4, ...

... patterns. The algebraic formulas we have found in this book are compact ways of describing a pattern. For example, the familiar equation (a + b) 2 = a 2 + 2ab + b 2 gives the pattern for squaring the sum of two numbers. Another example we have encountered is the pattern for the sum of the first n od ...

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.
