V1 op V2 = r		V1 op V2 % r	X =	X %
op	Vs		expa
+	V2	V1	X op Vs =	Vs op X %
-	V2	V1
×	V1	V1
÷	V2	V2		X op Vs %

expr	expa
X × =(%)	X × X ($X^{2}$)
X ÷ =(%)	1 ÷ X ($X^{-1}$)
X √	$\sqrt{X}$
X + =(%)	Vs + X
X - =(%)	Vs - X

Note:

• X - value on the display
• Vs - specific value
• op - operation
• r - result
• expr - expression
• expa - expantion
• Vs = 0 by default and changes with each operation
