k Equal Symbols and Unequal Symbols (=, ≠, <, >, <, >)
You can use these symbols to perform a number of different basic calculations.
Problem
Use this keyboard:
Operation
mth abc cat 2D
To add 3 to both sides of  MATH Cmd (X= 3 )+ 3 w
x = 3. x + 3 = 6
Subtract 2 from both sides OPTN MATH Cmd (Y 5 )- 2 w
of y < 5. y – 2 < 3
Tip
• In the “Syntax” explanations of each command under “2-7 Using the Action Menu”, the following
operators are indicated as “Eq/Ineq”: =, ≠, <, >, <, >. Whether or not the “Eq/Ineq” operators
include the “≠” operator is specified for each command by a separate note.
• An expression that contains multiple equation or inequality operators cannot be input as a single
expression. For output expressions, an expression can be output with multiple operators only in
the case of inequality operators that are facing in the same direction (example: –1< x <1).
Example: solve(x
2
– 1 < 0, x) w {–1 < x < 1}
k “with” Operator ( | )
The “with” (I) operator temporarily assigns a value to a variable. You can use the “with”
operator in the following cases.
•To assign the value specified on the right side of | to the variable on the left side of |
•To limit or restrict the range of a variable on the left side of | in accordance with conditions
provided on the right side of |
The following is the syntax for the “with” (I) operator.
Exp/Eq/Ineq/List/Mat|Eq/Ineq/List/(and operator)
You can put plural conditions in a list or connected with the “and” operator on the right side.
“≠” can be used on the left side or the right side of |.
