When adding two numbers, such as 123 and 423, care is taken to first line them up and then add like digits. How does expanding this expression to [(1 × 102) + (2 × 101) + (3 × 100)] + [(4 × 102) + (2 × 101) + (3 × 100)] make the operation more like a polynomial addition problem?

ohh maybe an example of a polynomial expression problem will help

if you change the 10 to Xs

so you see how with polynomial addition
dan815
  • dan815
we always add the like terms or the same degree terms we cannot add numbers infront of x^2 to x
dan815
  • dan815
so you see how addition is very similiar to the same thing we do with polynomial addition?

yeah I see now
dan815
  • dan815
theyre trying to show you how adding like terms is very similiar to the normal addition which we do already without thinking about it

ok i get it now i was just confused onhow polynomial addition works
dan815
  • dan815
k good
dan815
  • dan815
and in the future use latex or put ^ infront of exponents like 10^2 and 10^1

  • anonymous
oh ok will do :)
dan815
  • dan815
you should learn latex now, its good to start early

use those symbols
dan815

\[10^2\]

  • dan815
\[\int \frac{a}{b}dx e^x\]
