Curious Calculation and Mathematical Tricks

The video tutorial presents a curious calculation where you start by choosing a whole number between 1 and 1000, double it, add six, divide by two, and subtract the original number. The result is always three, regardless of the starting number. This calculation works for any integer, not just whole numbers within the specified range. A proof of this phenomenon is available in a linked video.

What is the first step in the curious calculation described in the video?

• Add six to a number

• Think of a whole number

• Subtract the original number

• Divide a number by two
