Performing Calculations Addition (+) Example: 6 + 7 = 13. [6] + [7] = 13 Subtraction (–) Example: 10 – 4 = 6. [1] [0] – [4] = 6 Multiplication (x) Example: 7 x 5 = 35. [7] x [5] = 35 Percentages (%) Example: Calculate 6% of 100. [1] [0] [0] x [6] % = 6 Example: Add 6% tax to $20. [2] [0] + [6] % = $21.20 Example: Calculate a 20% discount from $150. [1] [5] [0] – [2] [0] % = 120 Constant Calculations Press = to repeat last function. Example: Calculate 5 x 5 x 5 x 5 + 2 + 2 = 629 Press [5] x = = = + [2] = = 629 Profit Analysis Example1: If the cost is $19.95 and selling Price is $39.90, what is the profit mar...
