Step-by-Step Derivation of Basic Arithmetic

Let’s denote the first number as A and the second number as B. The operation is represented by Op.

1. Input Acquisition: The calculator first receives the value of A (the first number) and B (the second number) from the user.
2. Operation Selection: The user then selects an arithmetic operation (+, -, *, /).
3. Execution: Based on the selected operation, the calculator performs the corresponding mathematical function:
   • Addition: Result = A + B
   • Subtraction:100.625 / 4 = 25.15625

Financial Interpretation: Each person owes approximately $25.16. The calculator in iPhone 7 makes this multi-step calculation quick and easy, preventing awkward mental math or overpaying.

Example 2: Calculating Fuel Efficiency

You just filled up your car. Your odometer reads 45,230 miles. Last time you filled up, it read 44,980 miles. You put 12.5 gallons of fuel in your tank. What’s your car’s fuel efficiency (miles per gallon)?

• Step 1: Calculate miles driven.
  • First Number (A): 45230
  • Operation: Subtract (-)
  • Second Number (B): 44980
  • Result: 45230 – 44980 = 250 miles
• Step 2: Divide miles driven by gallons used.
  • First Number (A): 250
  • Operation: Divide (/)
  • Second Number (B): 12.5
  • Result: 250 / 12.5 = 20

Financial Interpretation: Your car achieved 20 miles per gallon. This quick calculation using the calculator in iPhone 7 helps you monitor your vehicle’s performance and fuel costs.
