Chapter 3: Scientific Calculations

Simulation Calculation (ALGB)

This function enables you to find different solutions quickly using different sets of values in the same expression.

Entering an expression for simulation calculation

The simulation calculation is used as follows.

1.Press b0to enter the NORMAL mode.

2.Enter an expression with at least one variable.

3.Press @G.

4.Enter the values of the variables. The calculation result will be displayed after entering the value for all used variables.

•You can use both global and local variables in your equation, but only local variables will be stored if you save the equation. (See page 58.)

•You need enter only the side of the equation that contains the variables.

•Performing simulation calculation will cause the variables memories to be overwritten with new values.

•The answer calculated will be stored in last answer memory.

•To exit simulation calculation, press j.

Changing a value of variables and editing an expression

When you are in the solution display, press eto return to the display for entering values of variables, then return to the equation display in the NORMAL mode by pressing j.
