Here's how it works: Assume that we have two variables a and b, and that: a = b. Multiply both sides by a to get: a2 = ab. Subtract b2 from both sides to get: a2 - b2 = ab - b2. This is the tricky part: Factor the left side (using FOIL from algebra) to get ( a + b ) ( a - b) and factor out b from the right side to get b ( a - b ).

The B.S. goes all the way back to the first two numbers you ever learned: 1 and 2. It turns out these seemingly separate digits are, in fact, exactly the same, and that 1 actually equals 2. And I

Here is a relevant excerpt: As you can see, it ends with "From this proposition it will follow, when arithmetical addition has been defined, that 1+1=2." The theorem above, ∗54 ⋅ 43 ∗ 54 ⋅ 43, is already a couple of hundred pages into the book (Wikipedia says 370 or so) I wrote a blog article a few years ago that discusses this in some

Complex Numbers This proof uses complex numbers. For those who are unfamiliar with them, we give a brief sketch here. The complex numbers are a set of objects that includes not only the familiar real numbers but also an additional object called "i".Addition and multiplication are defined on this larger set in such a way that i^2 = -1.So, although -1 does not have any square root within the

Principia Mathematica. A small part of the long proof that 1+1 =2 in the "Principia Mathematica". Some idea of the scope and comprehensiveness of the "Principia" can be gleaned from the fact that it takes over 360 pages to prove definitively that 1 + 1 = 2. Today, it is widely considered to be one of the most important and seminal works

The symbols had not been as formally defined until the book was written. It took until page 300 to define the symbols and to prove that they could put the symbols 1+1= together before proving that 1+1=2. They went to the basics of basic in this proof. including defining what a "1" is.

The book is Russel and North's Principia Mathematica, and the "300 pages" remark comes from the fact that the proof of 1+1=2 is roughly on page 300 with the first chunk of the book setting up notation, axioms, and proving other things. The actual proof basically says let 1 be the set containing sets of cardinality 1, similarly 2 is the

The standard model of arithmetic is N = {0, 1, 2, ... Now that we know that 1+1=2 is false every proof which depends on it is flawed. Flawed, not exactly wrong. The statements validated by proofs that depend on 1+1=2 may still be true, but the old proofs would not serve to stablish that truth. Lots of material would need being revised and

Principia does way more proofs than just this simple one (the proof 1+1=2 is really just falls out naturally, it isn't being specifically proven, if that makes sense). Firstly, Principia defines all of the mathematical language it uses, all of the different symbols and syntax, as well as literally defining logic itself (formal logic that is). I

Infinite + 1 = infinite Infinite + 2 = infinite. By transitivity: Infinite + 1 = infinite + 2. Subtract infinite from both sides and you get: 1 = 2. Proof of 0=1: Integrate 1/x dx by parts. (u=1/x, dv=dx). You get that the integral of 1/x dx = 1 + the integral of 1/x dx. Subtracting the integral from both sides yields 0=1.

0. You can! Math is axiomatic, so the exact proof would depend on which axioms you choose (some might choose 1 + 1 = 2 1 + 1 = 2 as an axiom itself, instead of a theorem). Whitehead and Russell's Principia Mathematica was an attempt to prove all of math from first principles. They famously got to showing that 1 + 1 = 2 1 + 1 = 2 on page 379.
