... 1. One die must be prime and the others 1; there are 3 choices for the prime (2, 3, or 5), and 3 choices for which die is prime, so 9 ways this can happen. There are 63 outcomes possible, so the probability is 9/63 = 1/24. (Answer: B) 2. For some A and B, 6x3 +5x2 +P x+Q = (x2 +1)(Ax+B) = Ax3 +Bx2 + ...

... To find a particular digit in a repeating decimal, note the number of digits in the cluster that repeats. If there are 2 digits in that cluster, then every 2nd digit is the same. If there are 3 digits in that cluster, then every 3rd digit is the same. And so on. For example, the decimal equivalent o ...

... Suppose that a column contains four lockers, numbered y, y + 1, y + 2, and y + 3, for some positive integer y. Then the sum of the locker numbers in this column is y + (y + 1) + (y + 2) + (y + 3) = 4y + 6 = 2(2y + 3) which is even. Since 123 is odd, then there must be two lockers in the column which ...

... 2. Counting Using Binary Numbers Consider how counting works in the decimal system. We start with 1 digit. We count using the numerals 0 through 9. After we reach 9, we've run out of numerals. So, we have to add a second digit. We start that digit at 1. Then we cycle the first digit through the nume ...

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.
