How many hundreds are in 48000 in mathematics by principles of place value through billions with solution?
480 hundreds.
Which of these branches of mathematics to obtain an optimal best solution to a problem that can be stated in a mathematical form?
There are no branches listed to select from!
How do you find the square root of negative numbers?
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.
What is pure math?
Pure Mathematics is the branch of mathematics that deals only with mathematics and how it works - it is the HOW of mathematics. It is abstracted from the real world and provides the "tool box" of mathematics; it includes things like calculus. Applied mathematics is the branch of mathematics which applies the techniques of Pure Mathematics to the real world - it is the WHERE of mathematics; it includes things like mechanics. Pure Mathematics teaches you HOW to integrate, Applied mathematics teaches you WHERE to use integration.
Why do you need mathematics?
You need mathematics to understand the universe, in all of its aspects. The universe itself is built upon mathematics. The elementary mathematics (arithmetic and elementary geometry) is needed to be known by all but the youngest of babies, for we use it in everyday life circumstances such as shopping, banking, driving or sports. Other advanced parts of mathematics are essential for some jobs. The thing about mathematics is that it allows us to model the world.What I mean by this is that an engineer takes a physical problem and converts it into a mathematical problem. He then uses the rules of mathematics to solve the problem. After he finds the mathematical solution, he then converts that mathematical solution into a physical solution.But you don't need to be an engineer to get a lot of use out of mathematics.When you pay for something at the store, the cashier does the same think as the engineer to figure out how much change to give you.She converts the problem into mathematical symbols. She calculates how much change to give you back, using mathematics. And then uses results of her mathematical calculations to give you back the correct change.Mathematics is extremely powerful, that is why you should learn as much as you can about it. The world has TVs, computers and everything else you like only because we had the power of mathematics to help us create it.
