Ok I’ll try to do my best to not go for random topics. The thing is I worry how much time it will take to learn a particular topic that I pick up. It gets overwhelming very quickly.
Can you tell me how to calculate how much time a particular topic takes so that I can relax in between my study...
I will be more specific in the future. Its negative numbers (integers) concept that I find unintuitive. I tried to learn by number line but I did not catch much. I searched other books but did not get it.
Its very informative site. Thank you @jedishrfu.
I actually don't know how to do it...
Can You recommend me one good book from each category namely pre algebra, algebra, geometry, arithmetic ?
I have Auffman, baker Introductory and intermediate Algebra book.

Hello, I was wondering how to check how much math I know and learn math up to High school level. Currently I am trying to learn the basic maths where I think i am weak. To give a light on how much i know, recently I learned that 1+1=2 is actually true. 1 cup + 1 cup = 2 cups. 2 cup - 1cup = 1...
@fresh_42 This totally is the case. I agree with you and Feynman. People here don’t explain in simple language and pour lots of information as a reply. This makes hard to understand and then they say we have pointed this or that out many times but you ignored. I don’t ignore. It gets lost into...
I saw.
and this proves my point. “Vast majority” always do what’s convenient. They would not understand inverse of a. Same thing with percentage. People understand 100. They are able to Compare things with 100. That’s why we use percent today.
That’s a mistake or typo.
Isn’t everything just addition?
Subtraction is addition of opposite. Multiplication is repeated addition and division is just opposite of multiplication which is also just addition.
Just because division is used by companies with big names doesn’t qualify division as a concept. It’s still multiplication.
They must have used it because its convenient.
Division has made life easier.
It’s for convenience that we teach division to kids. Actually what we are doing is inverted multiplication.
That’s what he meant by “to give all kids same number of cookie”. Division is for convenience.
If we are literally breaking down things into very basics then we are actually doing repeated addition. ##13## added ##13## times =##169##.
But we can save time and do direct multiplication.
For example what is ##\frac {169}{13} = ?##
This says “When ##169## is divided into ##13## groups how many there are in each group?”
This can be converted into a multiplication problem like this “##13## groups of how many in each group makes ##169##?”
This is ##13 * ? = 169##. It can be solved...
