Can You Solve This 1992 Math Test Equation?

A simple equation like 6 – 1 * 0 + 3 / 3 = 7 has baffled many. It looks easy, but without the correct approach, it’s a trap! The secret lies in following the PEMDAS rule:

• Parentheses
• Exponents
• Multiplication & Division (left to right)
• Addition & Subtraction (left to right)

Let’s break it down step by step:

1. Solve multiplication and division first:
   • 1 * 0 = 0
   • 3 / 3 = 1
2. The equation simplifies to: 6 – 0 + 1
3. Solve from left to right:
   • 6 – 0 = 6
   • 6 + 1 = 7

The result? 7, just as the equation states!

This classic math problem reminds us why understanding the order of operations is essential. So next time you face a tricky equation, stick to PEMDAS—and you’ll always get it right!
