Choose a number. Multiply by 2. Add 6 to the product. Divide by 2. Then subtract 3. What is the answer? Repeat this process using two different numbers.
start with x. The value after each step is listed below
x
2x
2x+6
(2x+6)/2 = x+3
x+3-3 = x
you always get your original number.
2
2(2)
4+6
10/2
5-3

Damn Daniel, How Does This Work
To solve this problem, let's go step by step with an example:
1. Choose a number, let's say 4.
2. Multiply it by 2: 4 * 2 = 8.
3. Add 6 to the product: 8 + 6 = 14.
4. Divide the result by 2: 14 / 2 = 7.
5. Finally, subtract 3: 7 - 3 = 4.
So, with the number 4, the final answer is 4.
Let's try this process again with a different number, let's say 10:
1. Choose a number, 10.
2. Multiply it by 2: 10 * 2 = 20.
3. Add 6 to the product: 20 + 6 = 26.
4. Divide the result by 2: 26 / 2 = 13.
5. Finally, subtract 3: 13 - 3 = 10.
So, with the number 10, the final answer is 10.
It's important to note that this process will always result in the original number you chose. This is because each operation undoes the previous one.
