... the base of the expansion. The most important cases are β = 2, 8, 10 and 16. We consider a few examples: Example. Rewrite in base 10. x = (1001)2 , y = (0.11111 . . .)2 , and z = (1 . . . 1)2 where z has k + 1 digits. Solution. We have x = 1 · 24 + 0 · 23 + 0 · 21 + 1 · 20 = (17)1 0. For y, we need ...

Estimating Sums and Differences When an exact answer is not
... Estimating Sums and Differences When an exact answer is not necessary, an estimate can be used. The most common method of estimating sums and differences is called “front-end rounding”, which is to round each number to its largest place value, so that all but the first digit of the number is 0.

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.
