Education / Re: Why Is 1+1 = 2,can Someone Prove 1+1=11? by xxx1: 12:35pm On Aug 01, 2009 |
natural numbers existed even before the creation of the world and mankind, Man only discovers them as time goes on, In the ancient time peoples tried to keep reord of that they own. That was when people started counting with fingers and toes, even with marks on the wall. There was no education then bt there was something we call informal education. i.e if a man has 1 goat he will make 1 mark on the wall. If he has 2 he will make 2(i.e 1'1). _____________________The proof starts from the Peano Postulates, which define the natural numbers N. N is the smallest set satisfying these postulates:________________ P1. 1 is in N. P2. If x is in N, then its "successor" x' is in N. P3. There is no x such that x' = 1. P4. If x isn't 1, then there is a y in N such that y' = x. P5. If S is a subset of N, 1 is in S, and the implication (x in S => x' in S) holds, then S = N. Then you have to define addition recursively: Def: Let a and b be in N. If b = 1, then define a + b = a' (using P1 and P2). If b isn't 1, then let c' = b, with c in N (using P4), and define a + b = (a + c)'. Then you have to define 2: Def: 2 = 1' 2 is in N by P1, P2, and the definition of 2. Theorem: 1 + 1 = 2 Proof: Use the first part of the definition of + with a = b = 1. Then 1 + 1 = 1' = 2 Q.E.D. Note: There is an alternate formulation of the Peano Postulates which replaces 1 with 0 in P1, P3, P4, and P5. Then you have to change the definition of addition to this: Def: Let a and b be in N. If b = 0, then define a + b = a. If b isn't 0, then let c' = b, with c in N, and define a + b = (a + c)'. You also have to define 1 = 0', and 2 = 1'. Then the proof of the Theorem above is a little different: Proof: Use the second part of the definition of + first: 1 + 1 = (1 + 0)' Now use the first part of the definition of + on the sum in parentheses: 1 + 1 = (1)' = 1' = 2 Q.E.D.
