p = 3.60 - 2(1.32) = 3.60 - 2.64 = 0.96 - Midis

Understanding the Context

Breaking Down the Equation: p = 3.60 – 2(1.32) = 0.96

The equation p = 3.60 – 2(1.32) = 0.96 follows the standard order of operations: parentheses first, then multiplication, followed by subtraction. Let’s walk through each step clearly.

Step 1: Solve inside the parentheses

Although there’s only one number inside the parentheses (1.32), clarification through multiplication ensures precision:
2(1.32) = 2.64

Step 2: Perform the subtraction

Now substitute back into the equation:
p = 3.60 – 2.64
Subtracting gives:
p = 0.96

Why This Calculation Matters

While this example appears simple, operations like subtraction and multiplication—especially with decimals—form the backbone of more complex mathematical modeling. For instance:

• Financial Planning: Determining net profits by subtracting expenses from revenue.
  
• Science and Engineering: Calculating energy, force, or material requirements where precisions of tenths or hundredths matter.
  
• Data Analysis: Cleaning and normalizing datasets may require repeated subtraction of constants or scaling factors.

Final Thoughts

Quick Tips for Solving Similar Problems

1. Perform Multiplications First: Always multiply inside parentheses before subtracting or dividing.
   
2. Use Decimal Alignment: Line up decimals neatly to avoid arithmetic errors, especially in budgeting or measurement contexts.
   
3. Double-Check Signs: Remember that subtraction is equivalent to adding a negative:
   a – b = a + (−b)
   This mindset prevents sign-related mistakes.

Real-World Application Example

Suppose a warehouse operator must calculate net inventory after two partial shipments:

• Initial stock: 3.60 units
  
• Shipment removed (represented by 2 × 1.32): 2.64 units
  
• Remaining stock (p): 3.60 – 2.64 = 0.96 units
