This article describes a technique for performing multiplication of equations with three digits on the abacus. Learn from an expert in the use of the counting tool.

The uses of math for the layperson are essentially endless. No matter whether you are a struggling student, a homeowner, or someone simply trying to lose weight, math is the universal language that has an something to offer everyone.

Finding the roots of a function is a very important operation in maths. For quadratic functions, there are a couple of ways to easily find the roots by hand.

The tangent line of a function in a point is a straight line that has the same slope as the function has in that point.

Solving triangles using Pythagoras's theorem, the cosine rule, the sine rule and various ways of calculating the area of a triangle.

This guide explains everything you need to know about circles, including calculation of area, segment area, sector area, length of an arc, radians, sine and cosine.

A look at what fractals are and three of the most popular examples: the middle third Cantor Set, the Koch curve, and the Sierpinski triangle.

There are many special types of numbers beyond the ones we commonly learn about, like square and prime numbers. The more rarely discussed types include perfect numbers, vampire numbers, Fibonacci numbers and narcissistic numbers.

Multiplying two matrices is different than multiplying just numbers. Because of these differences, the order in which the matrices are multiplied does matter. To be able to multiply two matrices, the dimensions must be right.

This article provides a technique for performing division using the abacus.

The French mathematician Émile Borel proposed a law about the probability of events occurring.

Working out the odds of an event occurring allows us to estimate the number of times that event will take place in future trials. Permutations/combinations are also an important part of the analysis.
