A First Digit Theorem for Square-Free Integer Powers
... exponent that converges asymptotically to a GBL with inverse power exponent. In particular, asymptotically as the power goes to infinity the sequences of squarefree integer powers obey Benford’s law. Moreover, we show the existence of a one-parametric size-dependent exponent function that converge t ...

... Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of MAFS.5.NF.1.1 fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In gener ...

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.
