• How can you train your brain to see arithmetic this way, after thinking of it differently your whole life?
• This isn't anything different, it's just expounding on what you've already learned to do. This is helpful for those who learn better by sight as they are able to "see" the regrouping in action.
• can you do different problems and can they make the same number?
• There is actually an end if you use fractional numbers and decimals.
• This is just to help people to understand how to regroup more. So if you are adding 34+58 you can tell you are going to regroup. First add the ones. 4+8=12
So take the one and put it over the 3, the 2 thats your ones place. Now, add 3+5+1=9. So your asnwer should be 92. Heres just some help. Also I agree with Kate
• These questions are so easy I just can't do them they just need to make this " Khan academy " more advanced I hope you know what I mean by that.
• what do you mean by more advanced
• 35 + 6 is 41 because it's the right answer, but it would be much easier if 30 + 5 + 0 + 6 = 41 because it's still the same.
• whats the circle around the ones for ?
• how to master mathemathics?

• Nobody can master arithmetic, or, mathematics, as you referred it to. But if you keep practicing and trying, you will get better every time. I guarantee it.
