I was careless when assuming 0! = 0

But if 0! = 0, it breaks the pattern, because n! times n+1 is always (n+1)!, and zero times anything is zero.

With this surely (n+1) = 1 because you have said that n = 0 and 0+1=1 and 1! = 1. Therefore 0! = 0

@Dennis Acreman – No, no, you don't add, you multiply. 3! = 2! x 3, 2! = 1! x 2, and 1! = 0! x 1. Since 1! = 1, 0! = 1 also.
Though it was to the 0th power. To the best of my knowledge, anything to the 0th power is always 1.
Same is the case with me... Hasty Nut, me
same here :(
This is my new knowledge 1!=0!

IF 1 ^ ௦ = 1 THEN 1^௦ = 1^1 GIVES ௦ =1 which is ABSURD. THE General Rule is x^௦ = 1 if and only if x not equal to 1.

So, if 1^1=1 and 1^2=1, then 1^1=1^2 gives 1=2? Your reasoning is absurd, 1^0=1.
One to the power of ANYTHING is one, just like zero times anything, such as two or three, is zero - but two does not equal three.

@Whitney Clark – FROM your POINT of VIEW 1^௦= 1=2^௦ HENCE 1 = 2. is TRUE

@Ramamurthy Tg – That is not my point of view. Zero times anything is zero, so in the equation 0x2 = 0x3, you cannot cancel zeroes and get 2=3. Similarly, one to ANY power is one, even though the exponents are different:
1 2 = 1 × 1 = 1 1 3 = 1 × 1 × 1 = 1 but 2 = 3 .
Similarly, anything (other than zero) to the power of zero is one.
@Ramamurthy Tg – This is exactly why x/0 is undefined! Going with Whitney's example real quick, 0x2=0x3, yes, but to get the equation down to 2=3, we'd need to divide both sides by zero! Which is why zero is undefined! Similarly, 2^0 = 1 = 3^0, but taking the log of every side, and pulling down the exponents, we get 0log2 = log1 = 0log3. Well, 0 times anything is 0, so we get 0 = log1 = 0. And log1 = 0 ! So there are no mathematical inconsistencies here; we're only proving the abstract nature of 0, and the fact that x/0 is undefined.
You missed the ! as did I. But I do digress this exponent is 0 by the power of NON divided by NON by the power of 0. 0x0div0x0 = 0 since you can't divide 0 zero times the answer remains the same.
according to your logic 2^0 = 1; 1^1 = 1; 0 = 1 So, does not this seem absurd as well ????? The rule X^0 = 1 should fit in every shoe

@Fred Burger – Yes, 2 0 = 1 and 1 1 = 1 . But how does this show that 0 = 1?

@Whitney Clark – Read Mr. Ramamurthy Tg's comment; I just quoted his/her hypothesis and tried to prove it wrong.
I missed it too, I unconsciously miscalcalculated
if 0/1=0 0=1*0 0/0=1?
Log in to reply
But 0/2=0; 0=2*0; 0/0=2? So 1=2? But in reality, division by zero is undefined.
0^0 also equals to 1 according to X^0=1 axiom hence 1/1 = 1
0! = 1
Therefore the equation can be rewritten as: (0^1)/(1^0)
Anything to the power of 0 (except 0) equals 1
Hence: 0/1 = 0
Great!
Just take care of the factorial sign(!) ie. 0!=1 and not ZERO and anything to the power zero is 1, so 1 to the power 0 is 1 itself!!
0! = 1; anything to the power 0 is also 1
I don't know much about factorials. Could you explain why 0! =1?
Log in to reply
Factorials are products of all positive integers from 1 to n. 0! is by convention 1 to account for empty product. An empty set is a set by itself.
I had the same question. A quick google sea ch revealed this. http://mathforum.org/library/drmath/view/57128.html
