The SOLVER feature is one of the calculator’s most powerful and distinctive features,

and helps you solve math problems with various analysis methods.

Using this feature, problems from linear equations to complex formulas can be solved

with ease.

To access the SOLVER feature, press 

@ '; to exit, press #.

• The SOLVER feature is not available in the Basic mode.

• The SOLVER feature shares variables with other calculator

features. These variables can be called up or defined within the

SOLVER feature OR any other features. For example, solving/

defining a value of “A” within the SOLVER feature will also

change the global value of “A”.

To switch your preferred analysis style:

1. Go into the SOLVER menu by pressing 

@ ' WITHIN

the SOLVER window. The SOLVER menu appears with four

menu items.

2. While A METHOD item is

selected on the left, select

your preferred method by

pressing 

1, 2, or

3.

The Equation method is useful when there is only one unknown

variable. For example, if you know the values of B and C for an

expression “A 

+

 B = C”, use the Equation method.

Determine the value of “C” in “A = 2B

2

 

+

 4C”, when A = 4, and

B = 5.
