... A prime number is a whole number greater than 1 whose only whole number factors are 1 and itself. Examples: 2, 11, 23 A composite number is a whole number greater than 1 that has whole number factors other than 1 and itself. Examples: 6, 15, 49 To factor a whole number as a product of prime numbers ...

... There are at least three strategies we can use to find LCM. Method 1 – List all the multiples of each number, circle the common ones and find the least of these. Method 2 – Write the prime factorization of each number, find the common factors and multiply, then multiply by each of the non-common fac ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
