This is a hard concept to understand, since infinity is not a definite number. It can keep carrying on forever, which makes it a surreal number.
However, 1 can be measured by infinity as well, due to the never ending amount of decimal places, for example, 1 x 10^-6 [0.000001], 1 x 10^-12 [0.000000000001] and so on.
So, since it is impossible to determine the boundary of infinity, for 1 and for infinity itself, it is most agreed that the result will still be infinity, for whatever sum or subtraction you do, excluding infinity - infinity (0).

ReneInfinity is not a number, but a concept representing something that is endless or boundless. Therefore, infinity minus one is still infinity, as subtracting one from something that is limitless does not change its magnitude. In mathematical terms, infinity is considered to be a value greater than any real or finite number, so subtracting one from it does not result in a finite value.

What is the value of infinite?
1 time infinity equals infinity. Infinite divided by infinite equals 1. There's your answer. * * * * * Except that it is not true. 1 times infinity is, indeed, infinity. But infinity divided by infinity need not be 1. See for example, the paradox of Hibert's Hotel at the attached link.
Does infinity have a limit?
No. That is why it is called "infinity". Infinity is actually not an accepted numerical value in calculus. It is rather a concept. For instance, (infinity) - 1 googleplex = infinity
What is 1 minus infinity?
Any specific number minus infinity is -∞ Note if you try to subtract infinity from infinity, the answer is undefined - because infinity is a "cardinality" rather than a specific number.
Is infinity equal to minus 1?
technically, infinity is not a value and therefore cannot be defined as minus 1. There is a notion that infinity does not actually exist but only a human myth applied to those values larger than the human can calculate eg the size of the universe. Quoting Hawkins phrase "the universe stretches on infinitely" shows that infinity is not minus one. Therefore, infinity is not equal to minus 1.
What does a number over infinity equal?
0. This is the same as the limit of 1/x as x approaches infinity, which is is 0. This is because 1/1,000 = .001 and 1/1,000,000 = .000001 and 1/100,000,000,000 = .0000000001 etc.
