Can you multiply infinity by infinity?

Yes, in most contexts, especially with limits in calculus, infinity multiplied by infinity ( ∞ × ∞ ∞ × ∞ ) equals infinity ( ∞ ∞ ), because it represents combining two endlessly large quantities, resulting in an endlessly large quantity. However, infinity isn't a standard number, so this is a conceptual result from limits (like lim 𝑥 → ∞ 𝑥 ⋅ 𝑥 = ∞ l i m 𝑥 → ∞ 𝑥 ⋅ 𝑥 = ∞ ), not arithmetic with real numbers.

What is ∞ ∞ ∞?

Addition Property. If any number is added to infinity, the sum is also equal to infinity. ∞ + ∞ = ∞ -∞ + -∞ = -∞

Is ∞ 1 bigger than ∞?

No. Infinity plus one is still infinity. But we can show that the number of points on the interval zero to one is a bigger infinity than the counting numbers are. The first clue is the fact that we can't count the number of points on a line interval.

What is 1 ➗ 0 and why?

1 divided by 0 (1/0) is undefined in standard mathematics because it breaks the rules of arithmetic; it doesn't equal a number like infinity (though limits approach infinity) and leads to contradictions, as you can't group things into zero-sized groups to make one. Division is repeated subtraction or grouping, and asking "how many zeros make one" has no answer, as adding zero always gives zero, never one.
 

Why is 52 an untouchable number?

The number 52 is an "untouchable number" because it's a rare number that can't be formed by adding up the proper divisors (all divisors except the number itself) of any other integer, making it a member of a special set of numbers that are "untouched" by this specific mathematical operation, joining other untouchables like 2 and 5 in this category. 

Mathematician Explains Infinity in 5 Levels of Difficulty | WIRED

Is tree 3 infinite?

TREE(3) is largely accepted to be one of the largest simply defined finite numbers, dwarfing other large numbers such as Graham's number and googolplex.

Why does .99999 equal 1?

0.999... (with infinite repeating nines) equals 1 because it represents the limit of a sequence getting infinitely close to 1, meaning there's no space between them on the number line; you can show this algebraically (let x = 0.999..., then 10x - x = 9, so 9x = 9, thus x=1) or by understanding that 0.999... is just another way to name the number 1, just as 1/3 is 0.333... 

Is the universe infinit?

Scientists don't definitively know if the universe is infinite, but current observations strongly suggest it's spatially flat, which points towards it being infinite or at least vastly larger than what we can see. While the observable universe (what we can see) is finite (about 93 billion light-years across), the total universe beyond that could go on forever, or it could curve back on itself like a torus (a donut shape) where you'd eventually return to your starting point after traveling far enough in one direction.
 

Is 3.14 infinite?

Its decimal representation goes on infinitely without repeating. The numbers following 3.14 carry on forever without forming any predictable pattern, which is why no one can write out pi in full. Computers have calculated trillions of digits of pi, yet we're no closer to finding an end.

Does 0x0 exist?

0× 0 × ____ =1 = 1 . There is no such number. We cannot find it because it doesn't exist. Since it doesn't exist, zero does not have a reciprocal, so dividing by 0 will not work.

Why is 1x1 not 2?

If 1 x 1 were 2, it would lead to inconsistencies and contradictions in basic arithmetic principles: Consider simple equations: 2=1+1 by definition. If 1×1=2 this would contradict the basic arithmetic addition we rely on.

What is ∞ x0?

But the limit is then 1 1 1 and not 0, and hence it is not necessarily 0. We could make this limit any value that we wish, which is why ∞ × 0 \infty\times 0 ∞×0 is undefined.

What is the unluckiest number?

There isn't one single "unluckiest" number globally, but 13 is famously unlucky in many Western cultures (triskaidekaphobia), linked to Judas at the Last Supper and Loki in Norse myth. In East Asia, particularly China, Japan, and Korea, the number 4 is highly unlucky because its pronunciation sounds like "death" (si), leading buildings to skip floors with 4, while 7 is unlucky in some places (like China) due to ghost month associations. 

Why is no 9 a magic number?

Nine is called a "magic number" due to unique mathematical properties in base-10, like the sum of digits of its multiples always reducing to 9, and its deep significance in various mythologies and cultures representing completion, transformation, and universal love. Its "magic" stems from the repeating pattern where any number multiplied by 9, when its digits are repeatedly summed (digital root), always results in 9, a concept tied to it being the last single digit before the base-10 cycle restarts.
 

Is 170141183460469231731687303715884105727 prime number?

Using this algorithm with hand computations on paper, Lucas showed in 1876 that the 39-digit number (2127 – 1) equals 170,141,183,460,469,231,731,687,303,715,884,105,727, and that value is prime. Also known as M127, this number remains the largest prime verified by hand computations.

How many zeros are in a googolplexianth?

There's no standard "googolplexianth" number; the "-ian" suffix usually denotes a power of a googolplex (like a googolplexian = 10^googolplex), so a "googolplexianth" would be a tiny fraction, but if you mean a googolplexian, it's a 1 followed by a googolplex (10^100) zeroes, a truly immense, unwriteable number represented as 10(10100)10 raised to the exponent open paren 10 to the 100th power close paren end-exponent10(10100).
 

Which is larger: million, billion, or trillion?

One trillion is a thousand billions, or equivalently a million millions. It is a 1 with 12 zeros after it, denoted by 1,000,000,000,000. One trillion seconds is 32,000 years. 5.

Is .99999999999 equal to 1?

It can be proved that this number is 1; that is, Despite common misconceptions, 0.999... is not "almost exactly 1" or "very, very nearly but not quite 1"; rather, "0.999..." and "1" represent exactly the same number.

What does Siri say if you ask 0 divided by 0?

Zero divided by zero (0/00 / 00/0) is mathematically undefined or indeterminate, as any number could technically be the answer (since any number times 0 is 0), but Siri often gives a funny, metaphorical answer, like the "sad Cookie Monster" scenario, because it's a nonsensical concept in basic arithmetic, as shown in these videos.
