High School Math Tip ✏️ | Absolute Value Made Easy

Evaluate an expression with absolute values.

Think clearly:
Absolute value means distance from zero
So the answer is always positive

Step-by-step logic:
• First, simplify what’s inside each bracket
• Then remove the absolute value sign by making numbers positive
• Finally, subtract

What happens here:
• One bracket becomes a larger distance
• The other becomes a slightly smaller distance
• Subtracting them gives a small positive result

✅ Final answer: 1

Key ideas to remember:
👉 Absolute value removes the negative sign
👉 Do what’s inside the bracket FIRST
👉 Think “distance”, not “minus”

📌 Clear logic beats memorization
