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 »

Linear function word problems are presented when a question is asked that requires students to figure out the linear function of a problem through words. These problems can be figured out more easily when they are transl... More »

A tape diagram is a visual way to solve word problems in mathematics, and the way to make one is to draw colored blocks to represent the quantities in the word problem. Redrawing the colored blocks an appropriate number ... More »

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 »

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 »

Scientific notation word problems ask the student to perform operations with two or more large numbers. For example, if light travels at 3 x 10^8 meters per second, how far will a beam of light travel in one day? More »

Linear algebra originated as the study of linear equations and the relationship between a number of variables. Linear algebra specifically studies the solution of simultaneous linear equations. More »
