Hi everybody,
I just want to make something clear: does juxtaposition always show multiplication? For example 2ab(c+d)e(pi)=2*a*b*(c+d)*e*(pi) ? Generally it applies to any multiplication as long as there are no confusions,despite the number of factors?(obviously 23 is not 2*3!) ?
And one more thing: when we write
a+b
---- we mean (a+b):(c-d) ? In other worlds the fraction bar shows that
c-d
everything that is above it, after it's calculated ,is divided with the final value of the expression under it, right? Is this always called a fraction?For example when a is irrational is it called a fraction? In any case every rule applied to fractions applies to this kind of "fraction" too? They are general rules of division?(example a a*c
- = ----
b b*c )
Thanks
