Positive/Negative Adventure: Balloons, Cauldrons & Slimes

Master Positive and Negative Numbers!

👉 Three-Stage Trial Rules:
🎈 [Hot Air Balloon (Stages 1-4)]: Subtract negative numbers (sandbags), the weight decreases, and the balloon flies up!
🍲 [Magic Cauldron (Stages 5-8)]: Add negative numbers (ice crystals), the temperature goes down!
🌟 [Slime Arena (Stages 9-12)]: What if there's not enough to subtract? Summon a "Zero-Sum Pair (1 Light + 1 Dark)" to help!

⚠️ You must predict the answer before operating! Correct prediction: +20 pts, Wrong: -5 pts. Successful operation: +10 pts.

🤔 Predict first: What should be the calculation result?
