    Question irrational numbers - HELP!!

    HELP!!

    What operations are available to irrational numbers?

    Can you arrive at a nonzero answer for addition? subtraction? Examples?

    Is sqrt of 3 times sqrt of 3 = 3 and a way to multiply irrational numbers?

    Is sqrt of 3 divided by the sqrt of 3 = 1 and a way to divide irrational numbers?

    Please help me if you can.

    irrational numbers have all mathematical operations available to them.
    pi for example is irrational.

    you can add and subtract pi
    you can divide and multiply pi
    you can squareroot pi and you can pi^x
    any mathematical operation you can do to a rational number you can also do to an irrational.

    sqrt(3) / sqrt(3) = 1

    Question More Help!

    Can you get a rational nonzero number with all operations? If so, do you have examples?

    Look man, u sound really upset -- be cool.

    You can do everything you like with irrationals. They are artificially constructed, OK. They are hard to grasp, OK. But they are manageable, as much as rationals are.

    Here are some facts you might like to ponder upon:

    a) rational + rational = rational

    b) rational + irrational = irrational

    c) 1/(rational) = rational

    d) 1/(irrational) = irrational

    e) (rational)*(irrational) = irrational

    f) If 1=2, then I am the King of France.
    Because, the King and I are two, therefore we are one.
