Under initial default settings, this calculator automatically simplifies fraction calculation results before displaying them. Before performing the following examples, use the Setup screen to change the "Simplify" setting from "Auto" to "Manual" (page 1-29). • When "a+bi" or "rQ" is specified for the Setup screen "Complex Mode" setting, fraction calculation results always are simplified before being displayed, even if the "Simplify" setting is "Manual". • If you want to simplify fractions manually (Simplify: Manual), make sure that the "Real" is selected for the "Complex Mode" setting.

I Solve Calculations [OPTN]-[CALC]-[Solve] The following is the syntax for using the Solve function in a program. Solve( f(x), n, a, b) (a: lower limit, b: upper limit, n: initial estimated value) There are two different input methods that can be used for Solve calculations: direct assignment and variable table input. With the direct assignment method (the one described here), you assign values directly to variables. This type of input is identical to that used with the Solve command used in the PRGM mode. 2-22
