Formula:
To perform arithmetic operations (addition, subtraction, multiplication, or division) on feet (ft) and inches (in):
Step 1: Convert to a single unit
Total Inches = (Feet × 12) + Inches
Step 2: Perform desired operation
Result in Inches = Total Inches1 (Operator) Total Inches2
(For multiplication/division, Total Inches2 acts as a scalar multiplier derived from the second input)
Step 3: Convert back to Feet and Inches
Feet = floor(Result in Inches / 12)
Inches = Result in Inches % 12 (remainder)
