Imaginary numbers are used in complex numbers that make some math simpler like electronics where there is a cycle frequency it makes the math much simpler to handle complex equations

Mathematics is beautiful in itself. Back in the 1700s and later, mathematicians studied "imaginary" numbers (numbers that involve a factor of the square root of -1) knowing that they didn't describe anything "real", the way "real numbers" do. But when beauty can be melded to practicality, things get REALLY interesting. It turns out that you can use imaginary numbers and "complex numbers" (which have a "real" component and an "imaginary" component) to describe the way radiation and electromagnetic fields behave.

algebra? The unknown numbers of which you speak are called variables. "algebra" oxford dictionary definition = investigation of properties of numbers using letters etc as general symbolsAll branches of mathematics have the opportunity to utilize letters instead of numbers. This is called a variable and they are found in every branch of mathematics.

Two of the most important numbers in mathematics, pi and e (Euler's number) are both transcendental. Both are used in almost all branches of mathematics, and through that, in our daily lives even if you are not aware of them.

In mathematics there are real and imaginary numbers. Real numbers include 55.7 as a tangible quantity, The imaginary and opposite number is (a negative or minus) -55.7.

See the answer to the related question: 'How do you solve the power of an imaginary number?' (Link below)

For most school mathematics, negative numbers do not have square roots. This is because a negative number multiplied by itself is a negative times a negative and so is positive. When (if) you study advanced mathematics, you will learn that there is a solution and this falls within the realms of complex mathematics and imaginary numbers.

the main branches of mathematics are algebra, number theory, geometry and arithmetic.

Many options - e.g. -2"Real number" means all the numbers we know, including positive and negative numbers.The only numbers that are not included are "imaginary numbers" - numbers that have an imaginary part i (used only i physics or high mathematics).See real-number

I dont know... but i have a question....what is the branches of mathematics? by maricar pauline v. mesa

No. Irrational numbers are real numbers, therefore it is not imaginary.
