You could use algebra in real life in nearly anything that you do. You could use algebra to calculate how much gas you will put in your car and how much it will cost you.
By definition, none. For if it did have real life applications it would not be called abstract! +++ You could consider it as establishing the rules by which the algebra needed to perform real-life tasks works. For a simple example, if C = AB then you could say, "Fine, suppose we call A and B the sides of rectangle than C is its area, OR if we call A and B speed and time respectively then C is the distance travelled. In both cases the algebraic rules are the same: multiply two values and you obtain their product; but many practical applications are in fact simple products so there we have the underlying pure algebra for solving them. And from that we can use pure algebra rules to determine A or B from the others.
shopping, travel, measurements and money are the real life applications of real number system.
Yes if it was not practical it was not there. You can see the real life use on this link http://www.intmath.com/Applications-differentiation/Applications-of-differentiation-intro.php
There are no real life applications of reciprocal functions
in real life what are applications of alanlytical geometry
There are many examples of daily life applications of real numbers. Some of these examples include clocks and calendars.
Many people learn algebra, and then never use it in their "real life". It's not that it COULDN'T be useful; but rather, that many people tend to forget how to use it. In some professions, you will DEFINITELY need algebra - as well as more advanced math.
