Mr. Mathemagician asks you to pick any whole number. Add 10. Multiply the result

by 4. Add 200. Divide by 4. Subtract your original number. Mr. Mathemagician says,
“You’re final result is 60!” Explain Mr. Mathemagician’s trick?

If you really want an expert to help you, be sure to follow directions and type your subject in the School Subject box. Any other words, including silly misspelled words, are likely to delay responses from a teacher who knows that subject well.

Mr. Mathemagician's trick involves a simple mathematical manipulation. Let's break it down step by step:

1. Choose any whole number (let's call it x).
2. Add 10 to this number: x + 10.
3. Multiply the result by 4: 4(x + 10).
4. Add 200 to the previous result: 4(x + 10) + 200.
5. Divide the entire expression by 4: (4(x + 10) + 200)/4.
6. Simplify the expression: x + 10 + 50.
7. Subtract your original number (x) from the simplified expression: (x + 10 + 50) - x.
8. Simplify further: 10 + 50 = 60.

When Mr. Mathemagician says the final result is 60, it is true because, regardless of the number you chose initially, the manipulation of adding, multiplying, dividing, and subtracting ultimately simplifies to 60.
