• What is infinite in real life. Like is there anything we can point to in reality that we know is truely infinite?
• In the world of surreal numbers and games, there are many varieties of infinity that are all meaningfully different from each other! Omega (which I'll call w) is what we usually think of as infinity. Varieties of infinity include but are not limited to w, w/2, squareroot(w), w - 1, w + 1, 2w, w^2, etc.

Have a blessed, wonderful day!
• why does 100 have 2 0
• It's because of place value. Zeros are place holders to make sure 1000 doesn't get confused with 100000000.
• Hey, fractions are 2/4 or 1/2 shayde.rakurku-hohepa.
• How to add quickly without thinking? Help.
• If you practice it a lot it will no longer feel like you are thinking about it
• Aren't counting numbers also known as whole numbers? Why are there two different names for the same thing?
• Like what Elizabeth Cummings said, counting numbers begin with the number one. This is the case because we cannot count with negative numbers. For example, I can't say that I have -2 apples.
Whole numbers are, by definition, numbers that don't have a fraction or decimal, because then, it wouldn't be whole. Whole numbers cannot be negative, and start with a zero.
• which is the biggest number ever !
• numbers go on and on forever, they never end.
• What is a quintillion?
• A quintillion is a number that is 1 followed by 18 zeroes(1,000,000,000,000,000,000.
• Why do we have a specific order of counting numbers,it could be just random also.
• If we didn't have a specific order of counting numbers, we would not be able to compare numbers. If we counted numbers in a random order, both 1 2 3 4 5 and 1 5 2 3 4 would be correct. In the first sequence, 2 is less than 5 because it comes first. In the second sequence, 5 is less than 2 because it comes first. How can 2 numbers be less than each other?
