Can you give me a link where I can read about it? I cannot find on google.

A power has two parts. Base and Exponent. A number 423 in base 10 can be written in other bases as well: 1. 4* 10^2 + 2*10^1 + 3*10^0 = 423 2. 1*7^3 + 1*7^2 + 4*7^1 + 3*7^0 = 1143 3. 7*60^1 + 3*60^0 = 73 All three expressions are equal in quantity. But I have written the multiplier of powers...

But that is what i am asking. A power has two parts. Base and exponent. 1. 4* 10^2 + 2*10^1 + 3*10^0 = 423 2. 1*7^3 + 1*7^2 + 4*7^1 + 3*7^0 = 1143 3. 7*60^1 + 3*60^0 = 73 All three expressions are equal in quantity. I am just trying to say that what we call place value system is we are writing...

1. It’s just the difference in placement of commas as much as I know. 2.It would be huge array of symbols in Roman.

Yeah. Can you shed some light on this ?

I think 423 is actually 4 hundreds 2 tens 3 ones but for convenience we don’t write hundreds, tens, ones. It’s easy if we define the concept of place value. For example 3rd place is hundredth place, 2nd place is tens place and 1st place is one’s place and just write 423 directly in short. 1...

In Indian 161 by 1007= 1,62,127. In Roman it would be CCC…(MVll times)LLL…(MVll times)XXX…(MVll times)lll…(MVll times).

I am just curious to know what was going in the mind of brahmagupta or aryabhatta that they came up with such a system that is efficient in representing numbers unlike roman numerals. Large numbers can be written with indian system but it would be difficult to do it in roman. It would create...

1. How did indians come up with such positional system ? Even though its simple but Looks mysterious. 2. Why 400 + 20 +3 is written as 423 ? Why have we omitted zeros ? 3. Why four hundred is written as 400 and not as 4 hundred or 4. Similarly why twenty is written as 20 and not as 2 ten or 2...

TL;DR Summary: What topics to cover to safely say I know arithmetic ? I am learning arithmetic from Indian NCERT textbook. Currently I have finished addition ,substraction of 2 digit numbers and divisions, multiplication of 1 digit numbers. I am moving pretty slowly. Can someone tell me what...

Yes and thank you. Thanks man.

Thanks😊 man

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...

Yes please.
