Worksheet 2 Answer Keys and Notes
... Solution: List the prime factors of each. 12: 2 x 2 x 3 80: 2 x 2 x 2 x 2 x 5 = 80 Multiply each factor the greatest number of times it occurs in either number. 12 has one 3, and 80 has four 2's and one 5, so we multiply 2 four times, 3 once, and five once. This gives us 240, the smallest number tha ...

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.
