āļø Be the judge of the math court! Not every math sentence is telling the truth. You must test both sides of the equals sign to smoke out the imposters.

An equation is only "True" if both sides of the equals sign (=) have exactly the same value! It's like a perfectly balanced seesaw. šÆ **Testing the Seesaw:** Look at this sentence: **14 - 6 = 9** 1. **Side A:** Do the math on the left side: 14 - 6 = 8. 2. **Side B:** The right side just says 9. 3. **Check the Balance:** Does 8 = 9? No! The seesaw is broken! This sentence is an imposter. It is **FALSE**. Look at this sentence: **7 + 8 = 15** 1. **Side A:** Do the math: 7 + 8 = 15. 2. **Side B:** The right side says 15. 3. **Check the Balance:** Does 15 = 15? Yes! Perfect balance. This sentence is telling the truth. It is **TRUE**.
