# What is Large numbers: Definition and 37 Discussions

Numbers that are significantly larger than those typically used in everyday life, for instance in simple counting or in monetary transactions, appear frequently in fields such as mathematics, cosmology, cryptography, and statistical mechanics. The term typically refers to large positive integers, or more generally, large positive real numbers, but it may also be used in other contexts. The study of nomenclature and properties of large numbers is sometimes called googology.Sometimes people refer to large numbers as being "astronomically large;" however, it is easy to mathematically define numbers that are much larger even than those used in astronomy.

1. ### Unimaginable Numbers: What is 1.36 x 10^495 times 20 Million?

Kurzesagt in a Nutshell said that the number of possible protein combinations the human body can have is 6.8 x 10^495. I asked GPT to multiple it by 20 million (which is the hypothetical number of possible alien civilizations in the Milky Way galaxy give or take). The chatbot gave me 1.36 x...
2. ### I Leading digits of incomputable large numbers

Was watching a youtube on Grahams number last night and its discoverer Ronald Graham. He talked about how many algorithms can calculate the ending digits of the number (its a power of 3) but the first digit is unknown. Guessing this is generally true of all incomputably large numbers that are...
3. ### I Is dealing with large numbers as formula a thing? and how is it done?

Hi everyone. I haven't been here in years, I'm surprised the account still works. Anyway. I have a mathematic thought/question that I really want to learn about. I realize this isn't going to be the easiest thing to explain if it is even possible, so please forgive me. So, What I want to do...

8. ### Python Adding very small values to very large numbers

I am using complex numbers and was wondering if there's any way that I can get output to match my exact input when performing basic arithmetic on them. For example, if I use type = complex_ or complex256, with A = 1. and B = 6.626 x 10^(-34), then C = A*B yields C = 6.626 x 10^(-34) as wanted...

15. ### Exploring Large Numbers: Comparing f(n) and g(n) as n Increases

which is greater as n gets large, f(n) = 2^{2^{2^n}} or g(n) = 100^{100^n} instinctively I'd go with f(n) but I have no idea of actually showing that f(n) would indeed get larger, obviously sticking in values of n doesn't particularly work. A method I was thinking was to show many digits...

24. ### Is There a Better Way to Remember Large Numbers?

I was just thinking why is it hard to remember a 15 digit number for example? (some people might not have trouble, but I think the majority would find 15 digits difficult without seeing it more than once). But I think it's because we assign an entire word to a number. For instance, remembering...
25. ### Gambling and the law of large numbers

Does the law of large numbers really apply directly to betting systems? For example, in American roulette the house advantage or "edge" is 5.26%, and smart players know that, as a consequence of the law of large numbers, you will lose 5.26 cents of every dollar bet in the long run. This is...
