What is infinite in real life. Like is there anything we can point to in reality that we know is truely infinite?(26 votes)
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.

why does 100 have 2 0(18 votes)
It's because of place value. Zeros are place holders to make sure 1000 doesn't get confused with 100000000.(20 votes)

Aren't counting numbers also known as whole numbers? Why are there two different names for the same thing?(6 votes)
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.(12 votes)

There is way more to math than this. There are negative numbers, decimals, fractions, percents, exponents, order of operations, four operations, geometry, trigonometry and more which brings me to my question. Which type of math is the hardest(4 votes)
It will depend on what you struggle, of course. It's like asking someone "what color is the worst" -- not everybody can agree.(5 votes)

- [Voiceover] Put seven
squirrels in the box. All right, so that's one, two, three, four five, six, seven squirrels. I've put seven squirrels in the box. Let's keep going, this is lots of fun. Put four squirrels in the box. That's even easier than putting seven. One, two, three, four. I just click on the squirrel and then drag it into the box. All right, hopefully we see more animals. Oh, here we go, horses. Put nine horses in the box. One, two, three, four, five, six, seven, eight, nine horses. It's a lot of fun.
