Step1: Think of any number. Step2: Subtract the number you have thought with 1. Step3: Multiply the result with 3. Step4: Add 12 with the result. Step5: Divide the answer by 3. Step6: Add 5 with the answer. Step7: Take away the number you have thought from the answer, that is, subtract the answer from the number you have thought.
So, here's my response to this Take any two ordinary constants. (e.g. x and y) Make them alike, as in x = y = any non-zero number (in this case, 2) Multiply each by y, but x works equally well (y²=xy). Subtract x² from each equation (y²-x² = xy-x²). Factor y²-x² into (y+x)(y-x) to make ((y-x)(y+x) = xy-x²). Factor xy-x² into x(y-x) to make ((y-x)(y+x) = x(y-x)). Divide by (y-x) to get (y+x=x). Subtract x from both sides of this equation to get y=0. This means that y=0. but since, y equaled 2 in the first case, that means 2 = 0. If you multiply this equation by 2.5, you get 5 = 0. Since 0 + 0 = 0, you can plug in 2 for the first two zeroes, and five for the last one, and then, TA DA! 2 + 2 = 5. Congratz, I just blew your mind. :ugeek:
