u lcm
Function: Obtains the least common multiple of two expressions
Syntax: lcm( {Exp/List}, {Exp/List} [ ) ]
○ ○ ○ ○ ○
To obtain the least common multiple of X 2 – 1 and X 2 + 2X – 3
Example
2(CALC)l(lcm)vx-b,
vx+cv-dw
u rclEqn
Function: Recalls multiple eqn memory contents.
Syntax: rclEqn( memory number [, ..., memory number] [ ) ]
○ ○ ○ ○ ○
Example To recall the contents of equation memory 2 and equation memory 3
3(EQUA)c(rclEqn)c,dw
• The memory numbers of equations produced as the result of a recall are not updated.
u rclAllEqn (rclAll)
Function: Recall all eqn memory contents.
Syntax: rclAllEqn
• The memory numbers of equations produced as the result of a recall are not updated.
u rewrite (rewrit)
Function: Moves the right side expression to the left side.
Syntax: rewrite( {Eq/Ineq/List} [ ) ]
○ ○ ○ ○ ○
To move the right side expression of X + 3 = 5X – X 2 to the left side
Example

X 3 + 3X 2 – X – 3
3X – Y = 7
3X + 6Y = 63
X 2 – 4X + 3 = 0
