Exercise 1
... Definition: let a, b be two integers. An integer d is called a common divisor of a and b if both a and b are divisible by d. Definition: let a, b be two integers, where at least one of them is not zero. The maximal common devisor of a and b is called the Greatest Common Divisor of a and b, and is de ...

Divisibility Rules – Blue Problems
... pairs: 1 x 36, 2 x 18, 3 x 12, 4 x 9, 6 x 6. But the last pair uses 6 twice, and when counting the factors of 36, we’d only count 6 once. Hence, 36 has an odd number of factors, namely 9. It helps to know that the number of factors for any prime to a power is one more than the power. For example, 35 ...

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.
