How and why are real numbers more difficult to represent and process than integers?

There are more real numbers than integers. The set of integers is countably infinite, of magnitude aleph-zero. The set of real numbers is uncountably infinite (specifically, aleph-one).A computer can't really represent real numbers (that would require an infinite amount of memory), rather, it uses an approximation.There are more real numbers than integers.

What are the applications of complex numbers?

There are numerous applications; you should read the Wikipedia article on complex numbers for more examples. Some applications include: Get a better understanding of math. Even if you do calculations with real numbers, working with complex numbers often gives a greater understanding.Electricity, with AC, uses complex quantitites.Quantum physicsArt - ever seen the Mandelbrot set, or other fractals?There are numerous applications; you should read the Wikipedia article on complex numbers for more examples.

A number that is not real?

That probably refers either to an imaginary number, or to a complex number. Despite the weird name, the "imaginary numbers" (and the complex numbers) have many uses in math and science.


What are some common uses for prime numbers?

There are few real-life uses for prime numbers. Nevertheless, they do have a useful purpose in some cases. For instance:Circada's only come out at time periods of 13 or 17. These are prime, and mean that a predator coming out at another value (say 4 or 6) will be less likely to catch them.Prime numbers are used to contact aliens. They are a simple but universal phenomenon that will indicate our intelligence.Prime numbers are used in encryption. It is much harder to crack a code with a big number that is the product of two large prime numbers than one which has lots of factors.


What are some real life uses for scientific notation?

Scientific notation is a short hand way of expressing numbers that are very large or very small such as 10,000,000 = 1.0*107 or 0.0000001 = 1.0*10-7

TCP is a protocol that uses those.


What is the difference between elementary algebra and Boolean algebra?

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
