• Math Input/Output Mode Input and Result Display in the Equation Mode
You can use the Math input/output mode in the Equation mode for input and display as shown
below.
• In the case of simultaneous equations (1(SIMUL)) and high-order equations (2(POLY)),
solutions are output in natural display format (fractions, ', π are displayed in natural format)
whenever possible.
• In the case of Solver (3(SOLVER)), you can use Math input/output mode natural input.
