Solver

To enter the Solver application, highlight the app using the directional keys. Press the ok key to enter the application. This application allows you to solve equations and systems of equations with both exact and numerical solutions. Enter an equation and receive the corresponding solutions.

The first screen of the application allows you to choose between Equations (for solving equations) and Finance (for solving financial calculations).

Equations

Solve an equation

Enter an equation

You may begin entering your equation as soon as you enter the application. You may also choose to utilize one of the equation templates. To use an equation template:

  1. Highlight Add equation.
  2. Press the ok key. The list of equation templates will appear. The templates may be modified to fit your needs.
  3. Highlight your desired template.
  4. Confirm with the ok key. Your equation template will now be located in the editing field.
  5. Use the directional keys and numerical keys to enter your desired equation.
  6. Confirm with the ok key.

To enter an equation without utilizing a template:

  1. Being entering your equation as soon as you enter the Equations application. You may utilize any lower case letter as a variable. To utilize x as your unknown value press the xnt key.
  2. Once you are happy with the equation you have entered, press the ok key to confirm.
  3. You may now add more equations, or highlight Solve the equation.
  4. Press the ok key to receive the result(s) of your equation.

To display the equal sign, press shift followed by the pi key. If you confirm without an equal sign in your equation, it will be added automatically.

Solutions

To obtain the solution(s) of your equation:

  1. Enter the equation(s) you wish to solve.
  2. Highlight Solve the equation at the bottom of the screen.
  3. Press the ok key to receive the solution(s).
Quadratic equations

If the input equation is a quadratic equation, the solutions are automatically given in an exact form.

The table will display the value of the discriminant for quadratic equations.

General case

Most often, solutions are computed numerically and their value is often approximated.

When you press the Solve the equation button, the application may require you to set an interval in which to search for the solution.

Set the values of Xmin and Xmax and highlight Solve the equation. Confirm with the ok key.

If there are many solutions, the calculator will only display the first ten.

Solving a system of equations

Entering a system of equations

You may enter more than one equation to be solved as a system. To enter a system of equations:

  1. Enter the first equation in your system.
  2. Confirm with the ok key.
  3. Highlight Add equation.
  4. Confirm with the ok key.
  5. Choose your desired template.
  6. Enter the second equation.
  7. Confirm with the ok key. Your second equation has been entered and the equations will be displayed as a system.

You may add up to 6 equations.

Solutions

The application solves linear systems with real or complex coefficients.

To obtain the solutions, highlight Solve the system at the bottom of the screen and press the ok key.

The application gives the solutions in exact form. It also indicates if there are infinitely many solutions or if there is no solution.

Finance

In the Finance part, you can choose the parameter to be solved in the context of simple or compound interest and then enter the data so that the calculator calculates the value sought.

  1. Choose Simple interest or Compound interest
  2. Choose the parameter you want to calculate
  3. Enter the known values
  4. Select Confirm to solve
