In mathematics, division by zero, division where the divisor (denominator) is zero, is a unique and problematic special case. Using fraction notation, the general example can be written as , where is the dividend (numerator).

What is 1 divided by 0? This is part of a series on common misconceptions. True or False? \frac10 01 is undefined. Why some people say it's true: Dividing by 0 0 is not allowed. Why some people say it's false: \frac10 = \infty. 01 = ∞. Can you see which of …

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...

Subtracting 1 from both sides, 1 = 0. What’s wrong with this “proof”? Presentation Suggestions: This Fun Fact is a reminder for students to always check when they are dividing by unknown variables for cases where the denominator might be zero. The Math Behind the Fact: The problem with this “proof” is that if x=y, then x-y=0.

2013年8月13日 · 1 << 0 is 1 shifted to the left by 0 positions, which is just 1. x << y - means shift bits of x to the left (to larger value) y times. In math, this looks like: x * (2^y) or x * pow(2, y) The << operator is a bit shifter. So 1 << 2, is equal to 4 as you take 1 and shift by 2 bits.
