Hi guys, I just want to verify about something that I find it sometimes hard ..
if we have ab what does it mean exactly ? lets assume I have 1+1+1+1+1 .. a times, then 1a=1+1+1...(a times) but what's confusing me is it include the first element that we add? I mean in my example of 1+1+1.... , will 1*a is the result of the whole sum of numbers of "1" with including the first element there(the first element of "1+1+1+... " is 1 because it's first element)?!)
thanks alot
