This tutorial will be able to help you evaluate the expression when given the values for each variable. You will learn how to substitute your variables and how to keep the operations although if not shown in order to find the solution to the expression. We also observe the order of operations, because we multiply first and then we subtract.

Making variables easier.

I am hoping I will learn how to do word problems related to Solving Systems of Linear Equations in Two Variables. It is an area I am having the most trouble.. especially related to distance (2 autos traveling at different speeds, etc.) problems where speed is unknown.

To learn how to work word problems, algebraic expressions with variables, rates,y=mx+b or y=mx-b, and knowing what these variables stand for on a graph, fractions conversions etc.
