a) That's hardly a 'proof' in the true sense.I absolutely hate proofs.

Seriously. Why do I have to prove even the most basic of steps of the equation.

b) If Einstein pulled e = mc² outta his ass without showing how he got there, no one would ever have believed him

c) Most maths proofs tend to skip the 'most basic steps' of the algebra.

d) Forget what your high school teachers told you about maths because they don't know what they were talking about.

It's been about 6 years since I've taken any sort of mathematics class. Trust me, I've long forgotten what I was taught in high school math.a) That's hardly a 'proof' in the true sense.

That's right, because there's more than one of them.*maths

It's wonderful how easily we can tell people who have seen math from people who haven't, isn't it?a) That's hardly a 'proof' in the true sense.

Too bad it stops working for some numbers under 5 as a multiplier.

of course it works! you just need 6 fingers and one negative finger... care to elaborate?

Jeff

x = 4

y = 4

based on the 'hand' logic, one could assume that:

if 0 fingers up equals 5, and 1 finger up equals 6, then -1 fingers up would equal 4:

-1 (fingers up) = x-5 = 4

or the other way around: if 5 fingers down equals 5, and 4 fingers down equals 6, then 6 fingers up must equal 4:

6 (fingers down) = 10-y = 4

so:

x * y = 10 * [ (x-5) + (y-5) ] + 1 * [ (10-x) * (10-y) ]

x * y = 10 * [ (4-5) + (4-5) ] +1 * [ (10-4) * (10-4)]

x * y = 10 * -2 + 1* 36

x * y = -20 + 36

x * y =

I realized it says to imagine the negative/extra fingers to make others work. Sorry my imagination must have shut downof course it works! you just need 6 fingers and one negative finger

4 times 4:

x = 4

y = 4

based on the 'hand' logic, one could assume that:

if 0 fingers up equals 5, and 1 finger up equals 6, then -1 fingers up would equal 4:

-1 (fingers up) = x-5 = 4

or the other way around: if 5 fingers down equals 5, and 4 fingers down equals 6, then 6 fingers up must equal 4:

6 (fingers down) = 10-y = 4

so:

x * y = 10 * [ (x-5) + (y-5) ] + 1 * [ (10-x) * (10-y) ]

x * y = 10 * [ (4-5) + (4-5) ] +1 * [ (10-4) * (10-4)]

x * y = 10 * -2 + 1* 36

x * y = -20 + 36

x * y =16(= 4 * 4)
