... The prime factorization of 18 is 32 · 2, so in order for a number to be divisible by 18 it must be divisible by both 3 and 2. First, in order for a number to be divisible by 3, the sum of its digits must be divisible by 3. In the case of x 15x , this means that x + 1 + 5 + x = 2x + 6 must be divisib ...

... *We are Factor Ninjas! We have come to FLMS to chop numbers into smaller numbers (their factors)! * *Helpful Hint: When finding factors, use your math facts! Start with one and the number itself. Then build up from one (2, 3, 4…). Once you get to a math fact that repeats factors you’ve already used, ...

... that can be used to find the mass of an object. For example, a table scale accurate to milligrams may be used for small objects, but a floor scale accurate to just grams may be used for a large object. A micrometer may be used to find the length of a microscopic object, but a kilometer may be used f ...

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.
