## Finally some good RSH news!

The good news is that even if RSH loses 1% for 100 days, it will still be worth \$1.72 a share, not zero.

That's how percentages work!

• Now let me prove to you that 2 = 1!

Let a = 1 and b = 1; ergo a = b.

Multiply both sides of the equation (a = b) by 1 in the form of a. The result is:

a squared = ab

Now subtract 1 from each side of the equation in the form of b squared. The result is:

a squared – b squared = ab – b squared

Now factor both sides of the equation.

(a + b) (a – b) = b (a – b)

The term (a – b) is common to both sides of the equation; so dividing both sides of the equation by (a – b) yields:

a + b = b

Since a = 1 and b = 1, the result of the preceding equation is 2 = 1

Just call me GENIUS!!!

• I just call you stupid. You take a whole page to state elementary school math. Your on ignore

• The 2 posters who note the proof’s division by zero are correct. Division by zero is prohibited. Congratulations to those 2 posters.

A few years ago I taught a graduate-level Cost Accounting course, and I put that proof on the blackboard. No student saw the flaw, and no one in the class pursued the matter even though common sense says that 2 of anything cannot be equal to 1 of the same thing. Moreover, no student in that class had heard of Socrates. How does one complete 16 years of schooling without at least having heard of Socrates?

The Lorentz transformation, which is a consequence of Einstein’s theory of special relativity, has a term that is 1 divided by the square root of 1 minus v squared over c squared, where c is the speed of light and v is the velocity of a moving body. As v approaches c, the denominator of the quotient approaches zero. V cannot reach c (otherwise division by zero would occur), which implies that nature has a built-in speed limit, it being the speed of light.

• You incorrectly factored the equation

From

a^2-b^2 = ab-b^2

the next simplification is

a^2=ab

then back down to a=b

• Cute but flawed. When you divide each side by a-b you are dividing by ZERO. You cannot do this so your reasoning is invalid.

• Please don't ask me to prove that a loss is equal to a gain. I haven't quite figured that one out yet, but I'm working it.

• lost one percent in one hour

• You should simplify your example. Suppose a share is selling for \$100. If it loses 50% per day for 2 days, it will not be at 0. It will be at \$25. Here's the math, and it's easy to follow:

Day 1: 100 -.5 x 100 = 50

Day 2: 50 - .5 x 50 = 25

So at the end of day 2, the share is selling at \$25.

• There is a long lost memory in my head about your example being part of an algebra question. Or maybe it was something else. Why you cannot reach infinity or absolute zero in this case. The problem is that in the real world the shares of some companies do go to zero.
