Mathematical equations called functions use input and output replace the variables in an equation. The input is the known variable, while the output is the solution. Use functions any time a variable (x) transforms in a ... More »

An accurate Math input output table consists of ordered pairs that correctly follow a specific rule. It is also known as a function table. People can determine missing values in the table by identifying the number patter... More »

Use input-output tables in fifth-grade math to help students learn the concepts of mathematical functions by plotting the values on a graph. Each input value, graphed on the horizontal axis, has a corresponding output va... More »

To write linear equations from word problems, the student must first decide which quantities to assign variables to, and then decide what operations must be performed in order to solve the problem. For example, the unkno... More »

A 3x3 system of equations solver is a tool that tells the user the values of three variables based on three equations. The user inputs the three equations, chooses which method to use and sees the results. More »

An extremely difficult math equation is the Jacobi-Madden equation, a4 + b4 + c4 + d4 = (a + b + c + d)4 where variables a, b, c and d can be any positive integer, negative integer or zero. The Jacobi-Madden equation is ... More »

One of the "cute" equations concerning love was introduced in the 1900 mathematical works of the British doctor, Havelock Ellis. Very simply, the equation provided the following formula: Love = Sex + Friendship. In 1956,... More »
