You can use CALC to save the types of expressions below.
• Expressions that contain variables
Example: 2X + 3Y, 2AX + 3BY + C, A + B i
• Multi-statements
Example: X + Y : X(X + Y)
• Expressions with a single variable on the left
Example: {variable} = {expression}
The expression on the right of the equals sign (input using
(=)) can contain variables.
Example: Y = 2X, Y = X
2
+ X + 3
• To start a CALC operation after inputting an expression, press the
key.
Example: To store 3A + B and then substitute the following values to
perform the calculation: (A, B) = (5, 10), (7, 20)
3 (A) (B)
(1) Prompts for input of a value for A
(2) Current value of A
5 10
(or )
7 20
To exit CALC:
• Note the expression you store is cleared whenever you start another
operation, change to another mode, or turn off the calculator.
Using SOLVE
SOLVE lets you solve an expression using variable values you want,
without the need to transform or simplify the expression.
Note that SOLVE can be used in the COMP Mode only.
