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).

Aug 13, 2013 · 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.

But multiplying by 0 gives 0, so that won't work. Once again, dividing by zero gives us difficulties! Imagine We Could Divide by Zero. Okay, let us imagine we can divide by zero, and see what happens. That means that things like 10 and 00 would behave like normal numbers. Try Multiplying By Zero. So let us try using our new "numbers".

Approaching from the right, \( \lim\limits_{x \to 0^+} \frac{1}{x} = + \infty. Approaching from the left, \( \lim\limits_{x \to 0^-} \frac{1}{x} = - \infty. In order for \( \frac{1}{0} \) to be consistent, the limits from both directions should be equal, which is clearly not the case here.

1 = 0. What’s wrong with this “proof”? 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 problem with this “proof” is that if x=y, then x-y=0. Notice that halfway through our “proof” we divided by (x-y).

One divided by a negative number closer to zero brings in a different result that is closer to negative infinity. Therefore, 1/0 = -infinity. Hence, one divided by zero has no answer which results in being undefined. Given below are some facts about division and zero.

Dec 10, 2023 · 1 Divided by 0: Here is the quotient and remainder of 1/0, along with the decimal result and percentage, including a calculator.

$\begingroup$ @BillDubuque arithmetically, $1/0$ simply means the inverse of $0$ for multiplication. While you can define $1/0$ in other contexts, usually by compatcification of plane or line, it's meaning is different than the arithmetic meaning.
