How do you Simplify Expressions How do you Simplify Expressions The equations section of QuickMath allows you to solve and plot virtually any equation or system of equations. In most cases, you can find exact solutions to your equations. Even when this is not possible, QuickMath may be able to give you approximate solutions to almost any level of accuracy you require. It also contains a number of special commands for dealing with quadratic equations. Solve The Solve command can be uses to solve either a single equation for a single unknown from the basic solve page or to simultaneously solve a system of many equations in many unknowns from the advanced solve page. The advanced command allows you to specify whether you want approximate numerical answers as well as exact ones, and how many digits of accuracy (up to 16) you require. It also allows you to eliminate certain variables from the equations. Plot The Plot command, from the Graphs section, will plot any function of two variables. In order to plot a single function of x, go to the basic equation plotting page,

What you have without the CAS is essentially an expensive TI-84 with a color screen, file management system, and a much improved TI-Basic programming language. In layman's terms, unless you have miss-typed the full title of you calculator, you cannot simplify expressions with your calculator. If you do have a the CAS version, it wouldn't be giving you an error. Also when you're in the calculator app, press Menu, then 3:Algebra, and you'll see all the functions for simple algebraic expressions and equations.
