Mastering Simple Algebra: Understanding the Calculation 243 – 3·32 + 3·1 = 150

Algebra doesn’t always require complex equations—sometimes, breaking down a straightforward expression helps build confidence in solving problems. Consider the equation:
243 – 3·32 + 3·1 = 150

At first glance, it may appear challenging, but a step-by-step breakdown reveals how simple math operations combine to yield a clear result. This example demonstrates foundational algebraic principles and how basic arithmetic supports more advanced problem-solving.

Understanding the Context

Breaking Down the Expression

Let’s look at the expression:
243 – 3·32 + 3·1 = 150

The order of operations (PEMDAS/BODMAS) means we evaluate multiplication before subtraction and addition:

  1. First, perform the multiplications:
    • 3 × 32 = 96
    • 3 × 1 = 3
