Performance ：
1. The magician presents five cards, each filled with various numbers in different colored blocks (Red, Green, Yellow, Purple).
2. The audience is asked to choose one number from each card and cover them up with an object so the magician can't see them. (The only rule: each choice must be from a different color block).
3. Without seeing the hidden numbers, the magician instantly calculates and announces the exact sum of all five chosen numbers! It looks like pure genius-level mental math.

Revealing Secrets ：
1. The secret isn't hard math—it's a simple hidden formula.
2. The Magic Constant: For this specific set of cards, the total sum always revolves around the number 210.
3. The Cheat Sheet: You only need to look at the number in the Red block that remains visible or is indicated on the final card.
4. The Secret Key:
If the Red number is 31, the sum is 179.
If the Red number is 38, the sum is 172.
If the Red number is 47, the sum is 163.

Pro Tip: You’ll notice a pattern (31 + 179 = 210 ，31+179=210 ).

Simply subtract the visible Red number from 210, and you have your answer! Just memorize these few pairs, and you’ll look like a math prodigy.
