Mathematics (round of applause from me, boos from crowd)

"At 60 mph, it takes 60 seconds to travel a mile. At 120 mph, it takes 30 seconds. At what speed would it take 45 seconds?"

I will re-phrase the question in terms of race car drivers Alice, Barbara and Carol:

--> Race car driver Alice drives at 60 mph and takes 60 seconds to travel one mile.
--> Race car driver Barbara is much faster and drives at 120 mph; it takes Barara 30 seconds to travel one mile.
--> Race car drive Carol has a broken speedometer but travels one mile in exactly 45 seconds. What was her speed?

75 miles per hour.

didnt show your work but... your you so we let it slide;)

try this then...

Snap your fingers. Wait 1 second. Snap again. Wait 2 seconds. Snap again. Wait 4 seconds. Snap again. Each time, your "wait" will be double the previous time. Do this for one year. How many times will you have snapped your finger?

I like maths. :)

I got a A+ for it, on my report. :D

The only reasons is;

1) My math teacher rocks and,

2) It's quite easy, if you listen to the explaining done..

Oh, and a lot of people in my class still fail maths..

But a positive number is the opposite of a negative number, and a negative number is the opposite of a positve number. This will make the same situation as the "True/False".

So if a lie is true, it must be this.

-2x2= -2

If the equation ends with a negative number, it is therefore a lie.

But if a truth is a lie, it is this.

2x-2= -2

See. It is a lie.

And if a lie is a lie, it must be this.

-2x-2= 2

So there, if a lie is a lie, then is must be a truth.

I don't think you get what I was trying to say in my first post.

-x^2 = x^2

-X can be replaced with "lie, false, falsity, not, etc..." X can be replaced with "truth, fact, true, real, etc..."

By saying (-x)(-x) = (x)(x), you are saying

"A not lie is a true fact."

Because if something is not a lie, it is a fact.

I hope that makes things clearer.

Snap your fingers. Wait 1 second. Snap again. Wait 2 seconds. Snap again. Wait 4 seconds. Snap again. Each time, your "wait" will be double the previous time. Do this for one year. How many times will you have snapped your finger?

y = 1 * 2^(x-1)
y = (1 * 2^x) - (1 * 2^(x-1))
3.154x10^7 = (1 * 2^x) - (1 * 2^(x-1))

Would you snap your fingers 25 times?

Or is the opposite of a number the "inverse?"

Is the "opposite" of 4, either -4 or 1/4?
4 + -4 = 0
4 x 1/4 = 1

They both have opposing properties. Which equates more to truth/lie?
I'm not answering the question, yet. It seems like a fair, and potentially fun debate. :)

4 x 1/4 = 1

This is at the multiplying/dividing perspective

4 + -4 = 0

This is at the adding/subtracting perspective

Since 4 plus -4 is 0, this means that they are opposites. But 4 divided by 1/4 is 1, and is therefore not an opposite.

I completly agree with Milo over there.

I assume you just missed the not, it's an easy mistake to make.

But if you're going to compare division for inverses, then shouldn't we also look at subtraction for negatives? 4 - (-4) = 8 It doesn't equal 0, just like 4 divided by 1/4 doesn't equal 1
