Examples:
50x20% means 20 percent of 50 (or use the shorthand 50%20) = 10
10-20% means subtract 20% of 10 from 10 = 8
10+12% means add 12% of 10 to 10 = 11.2
• Square Root (F2).
Example, 9√ = 3, or 3+9√ = 9

Example, 9² = 81
• Reciprocal ⅟x
Example, ⅟4 = 0.25
• +/- (F3) - negates the value

Example: (3+2)*4 = 20 without parenthesis the multiplication happens first: 3+2*4= 11
