Here's what happens according to the math: If x = -1, then -(-1) = +1, making -x = +1. It's the plus-minus parentheses rule! (Think of the 2 minuses & the opening parenthesis coming together to form a plus sign!) Also, the product of 2 negative real numbers is always a positive real number! (With imaginary numbers, 2 negative imaginaries give a negative real number, but a negative imaginary multiplied by a positive imaginary gives a positive real product, too!)
Have you seen the Web page about the irrational number φ(Phi) yet? This number is also known as the Golden Ratio. It's approximately equal to 1.618; however, since it's irrational, there are no repeating patterns of digits after the decimal point! Also, if it was rational, the digits would eventually terminate; but they never do. (Padding zeroes after the decimal point are unconsidered since 1.0000... = 1, no matter how many zeroes you put afterwards.) What significance does this number have in this Web page, too? Well, let's consider another unique number you get by adding 1 to its additive inverse! Let's call that number Qi!
Notice how the value of the variable (œ(Qi)) is negative instead of positive. That makes -œ(Negative Qi) positive! Wonderfully weird, isn't it?
Phi | Qi | Sum |
+φ | +œ | +1 |
+φ | -œ | +√(5) |
-φ | +œ | -√(5) |
-φ | -œ | -1 |
Plus, this fact about negative numbers vs. positive numbers still DOESN'T get falsified!:
If X > Y, then -X < -Y
