There are very many uses for Irrational Numbers. A square, whose sides are a rational number, will have a diagonal of irrational length. The diagonals of most rectangles, with rational sides, will be irrational. The circumference and area of a circle (or ellipse) is related to pi, an irrational number. In the same way that pi is central to geometry, another irrational number, e, is fundamental to advanced calculus.

Here are the basic differences:elementary algebra:- Domain is the real numbers- Uses the operations of addition, subtraction, and multiplication- Uses the laws of associativity, commutativity, and distributivityBoolean algebra:- Domain is only two numbers- Uses the operations of conjunction, disjunction, and negation (AND, OR, NOT)- Uses the laws of associativity, commutativity, distributivity, absorption, and complements
Our day starts with numbersand ends it with numbersEvery minute of our life revolve around numbersAnd they hold the potential to change our lives too.Real numbers have uses tooIt helps us solve Mathematical ProblemsIt helps us to save our money and budget our moneyAnd it make us a wise consumer.

You work as a house painter. When you set up your ladder, you like to set the base 5-ft from the wall, for stability. How high on the wall can you reach with a 12-ft ladder ? With a 15-ft ladder ? With a 30-ft ladder ? ============================================================== The question is not: Can the Pythagorean Theorem help you in real life ? The question is: Is your life real enough yet that you can use the Pythagorean Theorem to make it easier ?
