uabsExpand [Action][Equation/Inequality][absExpand]

Function: Divides an absolute value expression into formulas without absolute value.

Syntax: absExpand(Eq/Ineq [ ) ]

Example: To remove the absolute value from 2x – 3 = 9

uandConnect [Action][Equation/Inequality][andConnect]

Function: Combines two equations or inequalities into a single expression.

Syntax: andConnect(Eq/Ineq-1, Eq/Ineq-2 [ ) ]

Example: To rewrite x > –1 and x < 3 into a single inequality

ugetRight [Action][Equation/Inequality][getRight]

Function: Extracts the right-side elements of an equation or inequality.

Syntax: getRight(Eq/Ineq/List [ ) ]

Example: To extract the right side elements of y = 2x2 + 3x + 5

ugetLeft [Action][Equation/Inequality][getLeft]

Function: Extracts the left-side elements of an equation or inequality.

Syntax: getLeft(Eq/Ineq/List [ ) ]

Example: To extract the left side elements of y = 2x2 + 3x + 5

uand [Action][Equation/Inequality][Logic][and]

Function: Returns the result of the logical AND of two expressions.

Syntax: Exp/Eq/Ineq/List-1 and Exp/Eq/Ineq/List-2

Example: To obtain the result of the logical AND of x2 > 1 and x < 0

uor [Action][Equation/Inequality][Logic][or]

Function: Returns the result of the logical OR of two expressions.

Syntax: Exp/Eq/Ineq/List-1 or Exp/Eq/Ineq/List-2

Example: To obtain the result of the logical OR of x = 3 or x > 2

uxor [Action][Equation/Inequality][Logic][xor]

Function: Returns the logical exclusive OR of two expressions.

Syntax: Exp/Eq/Ineq/List-1 xor Exp/Eq/Ineq/List-2

Example: To obtain the logical exclusive OR of x < 2 xor x < 3

unot [Action][Equation/Inequality][Logic][not]

Function: Returns the logical NOT of an expression.
