How Do You Multiply By Zero?

What is the value of 0 * infinity?

Like wise inf*0 can assume any values, which means that 0*inf is undefined.

This also points to the fact that infinity is not a number , rather a concept and hence multiplication does not hold any meaning in this case, as proved above.

Remember that although infinity is a concept, a number can tend to infinity..

Is anything divided by 0 infinity?

Dividing by 0 (as in exactly zero) does not give you infinity, the result is called undefined. The reason for it being undefined is this. … That means if you take the limit as the divisor approaches zero from both sides you get a discontinuity at zero where it is simultaneously positive infinity and negative infinity.

Why something divided by zero is infinity?

Infinity is not a real number, and even if it were, it wouldn’t be the answer to dividing something by zero. There is no number that you can multiply by 0 to get a non-zero number. There is NO solution, so any non-zero number divided by 0 is undefined.

What is 1 divided infinity?

Essentially, 1 divoded by a very big number gets very close to zero, so… 1 divided by infinity, if you could actually reach infinity, is equal to 0.

Is 1 0 undefined or infinity?

In mathematics, expressions like 1/0 are undefined. But the limit of the expression 1/x as x tends to zero is infinity. Similarly, expressions like 0/0 are undefined. But the limit of some expressions may take such forms when the variable takes a certain value and these are called indeterminate.

Who invented 0?

Brahmagupta”Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628,” said Gobets. He developed a symbol for zero: a dot underneath numbers.

Can you multiply by 0?

The rule is that anything multiplied by 0 is equal to 0. Remember this rule, and all multiplication by 0 problems will become instantly easier. If you see 0 in your multiplication problem, then your answer is 0.

Can you multiply infinity by 0?

In actuality, when any number (including zero) is multiplied with infinity, then the results are always undefined. Therefore, zero times infinity is undefined. So, zero times infinity is an undefined real number. This is the definition of undefined.

What does Siri say when you ask her what 0 0 is?

If you ask Siri this question in the iOS 8 operating system, the iPhone’s virtual assistant will cleverly tell you that you’re making no sense. Support our journalism. Subscribe today. “Imagine that you have zero cookies,” Siri’s response begins, “and you split them evenly among zero friends.

What is infinity to the power of 0?

In that case infinity to the power of zero is 1 because any Real NUMBER to the power zero is 1. But when you calculate limits, infinity to the power zero is indeterminate.

Is zero a number Yes or no?

Zero is not positive or negative. Even though zero is not a positive number, it’s still considered a whole number. … So, to answer the question is zero a natural number – yes it is on a number line and when identifying numbers in a set; but also no, because it’s not used to count objects.

Is 0 A infinity?

Since you are having this confusion, I think it helps to consider the concepts of zero, infinity and “undefined”. … This obviously makes no sense – we say that 0 / 0 is “undefined” because there isn’t really an answer. Likewise, 1 / 0 is not really infinity. Infinity isn’t actually a number, it’s more of a concept.

Why can you multiply by zero but not divide?

Dividing by zero isn’t allowed because it results in the same answer (infinity) for every input and therefore is considered “undefined.” Multiplying by zero is allowed, even though it results in the same answer for every input (zero).

What is the answer to something divided by 0?

In ordinary arithmetic, the expression has no meaning, as there is no number which, when multiplied by 0, gives a (assuming a ≠ 0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 00 is also undefined; when it is the form of a limit, it is an indeterminate form.

What happens when you multiply by 1?

The Rule. If you noticed, when you multiply by 1, you always get your original number. 38 * 1 is equal to 38, and 431 * 1 is equal to 431. … This rule tells us that anything multiplied by 1 is itself.
