What is infinite in real life. Like is there anything we can point to in reality that we know is truely infinite?(42 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.(16 votes)
Aren't counting numbers also known as whole numbers? Why are there two different names for the same thing?(11 votes)
Counting numbers are also known as natural numbers, and are a different set of numbers than whole numbers.
Counting, or natural, numbers are 1, 2, 3, 4, 5, 6, 7, 8, ... (i.e., no negatives or partials).
Whole numbers include all natural numbers, as well as the number 0.
Integers include all whole numbers, and their opposites (i.e., 0, 1 and -1, 2 and -2, 3 and -3, etc.)
There are more sets of numbers, and it can be helpful to think of them in a different context. For example, you might check out this video to see a helpful visual and comparison https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-numbers-operations/cc-8th-irrational-numbers/v/categorizing-numbers.(8 votes)

Which method do you guys prefer when counting? Using your hand or picturing it on your mind?(1 vote)
Picturing it in my mind. I find it more useful when I am taking the Linear Algebra course of Khan Academy.(6 votes)
what does the word counting come from?(3 votes)- it comes from Middle English (as a noun): from Old French counte (noun), counter (verb), from the verb computare ‘calculate’ (see compute).(4 votes)
Does anyone know how to count using bar line?(4 votes)- You count using the number line by going to the next number in the line. That's the next number to the right of where you start. So, you start at 0 and move right to the next number for each number you want to count. (0), 1, 2, 3, 4, 5. Remember to start with 0 or it won't work. You can add numbers using a number line by starting with one of the numbers you are adding and then count to the right using the other number that you are adding. 2 + 3 would be (2), 3, 4, 5. Good luck!(3 votes)

Why is it that literally everyone who has commented on this video is long out of this course? It would make more sense for there to be nobody commenting on this video.(1 vote)- Hmm any suggestions on how i could improve this method of learning how to count? my friends son is learning how to count but not at a fast rate.(0 votes)
- Khan is a great place to practice skills, however if he is struggling with the exercise here try a more hands on method. grab 10 -20 of his favorite groups of toys( legos, cars, dinosaurs, something that is a high interest item for him.) Divide into two pile have the child count one and the parent count the other then let the child tell you who has more. Rise and Repeat :) A favorite small healthyish snack works well too ( cereal, goldfish, raisins.)(6 votes)
- Are there keyboard shortcuts available to solve the exercise shown in this video without the need of a mouse?
Most exercises on this site seem to be solvable with only the need of a keyboard using tabbed navigation and other similar shortcuts, but I can't tell if that's the case with this one. This might not be an issue at all to most users but it's not that uncommon for someone to be using a portable notebook with a faulty or disabled trackpad(0 votes)- Press the "enter" button.(0 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.
