1 + 1 = 0: The Proof! I've seen a few so-called "Maths tricks" on YouTube, most involving division by zero or basic algebra, so here's my contribution. You do need to know a bit about square...

There are fields in which 1+1=0 - this property is called characteristic 2. More generally, for any prime p p, there are fields in which 1+1+ . . . +1 (p p times) equals 0; see https://en.wikipedia.org/wiki/Characteristic_ (algebra).

The following is a “proof” that one equals zero. Consider two non-zero numbers x and y such that x = y. Then x 2 = xy. Subtract the same thing from both sides: x 2 – y 2 = xy – y 2. Dividing by (x-y), obtain x + y = y. Since x = y, we see that 2 y = y. Thus 2 = 1, since we started with y nonzero. Subtracting 1 from both sides, 1 = 0.

I know there is a really similar question out there, but I can't find any contradiction with the field axioms if 1 + 1 = 1 instead of 0. Can someone explicitly show me the logic behind why 1 + 1 = 0 over the binary field and not 1 or 2?

2023年10月14日 · Use this basic calculator online for math with addition, subtraction, division and multiplication. The calculator includes functions for square root, percentage, pi, exponents, powers and rounding. How to do repeating operations, higher powers and roots, memory and clear functions for this standard calculator are explained below.

There are multiple measures of what that comes to but intuitively you might think that the value alternates between 1 and 0, so you could call it a half. In truth this series never converges on any given number.

2015年4月12日 · 1+1+1+1+1= 5. 1+1+1+1+1 =5. 1+1x0+1= 2. The first two are clear. The third line requires that you know that there is an order of precedence for arithmetic operations. In our case the multiplication must be done first and then the addition. The total rule is given in the mnemonic "pemdas"

In mathematics, the infinite series 1 − 1 + 1 − 1 + ⋯, also written is sometimes called Grandi's series, after Italian mathematician, philosopher, and priest Guido Grandi, who gave a memorable treatment of the series in 1703. It is a divergent series, meaning that the sequence of partial sums of the series does not converge.

63 Explanation: Use PEMDAS to solve. Start inside the parentheses and subtract 10 from 1: 1−10 = −9 Now multiply −9 by −7 ...
