1
Why there isn’t a “imaginary” number for absolute values…
2
What is an imaginary number? An imaginary number, is a number that doesn’t work in the normal rules of algebra, doesn’t exist in our normal number system, and can’t be counted to (by using natural numbers).
3
What is an example of an imaginary number?
4
So about absolute value…
5
Why won’t that work? The absolute value of a number is the distance that number is from zero. Think would it make sense to say: “I am -9 meters away from you”? It would make sense if you said: “I am -9 meters in front of you” or “-9 meters behind you” but you can’t be -9 meters away from something. That is why absolute value exists and can’t be a negative number.
6
Photo example: -9 meters apart IT DOESN’T WORK!
7
So… If you draw a line, square, cube, tesseract, etc. no matter where you put your point, no matter what dimension your graph is in, Your point can never be a negative distance away. It is impossible, even for an imaginary number to be a negative distance away from something.
