There are an infinite amount of numbers, so no one single number is the largest. But if we were to put every possible digit in 1 digit, then this will come out as infinity.

Infinity-1=Infinity

but 10 - 1 = 9

But the number is infinite

So if
infinite - 1 = infinite

I can subtract infinity from both sides and get

-1 = 0

I can multiply both sides by -1 now and also get

1 = 0

We don't know what infinite even means. In some crazy way this is possible in infinity land.

Infinity is essentially a never-ending variable. The solution to infinity minus one is infinity. However, what mathy showed was also correct, just for a slightly different problem. What mathy showed was the solution to "infinity - 1 = infinity", where you would be trying to find the variable. Infinity is not a set number, so if you subtract 1, it will still be infinity. However, something to note in mathy's version is that you wouldn't subtract infinity from both sides, you would add 1 to each because you are trying to find a variable, not 1. But it is impossible to add or subtract a set number from an unset number. So you get infinity = infinity.

If infinity is not a number, but just a concept, then you can't add or subtract a real number ('1') to it since that would not be a legal math operation. Infinity may not even exist. It is an abstract concept in math that helps explain things, like solving hard equations by setting something to infinity so a fraction goes to zero giving you an answer. It is often used as a convenient tool. Nobody can ever prove it exists physically. Maybe it represents a higher power or something we can't even imagine as simple humans. infinity + 1 = infinity has no physical representation, so you can't prove it exists.

Essentially, yes, it's a concept. Personally, as I said, I view it as a large variable because we don't know exactly what it is, just that it's big.
