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

After doubling the number, what is the next step in the calculation?

• Subtract the original number

• Add six to the result

• Divide by two

• Multiply by three

What operation is performed after adding six to the doubled number?

• Multiply by two

• Subtract the original number

• Divide the result by two

• Add the original number

What is the final result of the calculation, regardless of the starting number?

• The original number

• Six

• Zero

• Three

What is the significance of the calculation's result?

• It is a method to find prime numbers

• It only works for numbers between one and one thousand

• It demonstrates a mathematical trick

• It shows how to multiply numbers quickly
