Why are imaginary numbers important?
They are used for working out equations where the numbers you are working with are not physically possible, but we just imagine they are, such as the square root of a negative number In engineering, especially Electrical Engineering, using complex numbers to represent signals (rather than sines and/or cosines) make comparing and working with signals easier.
Give an example of a not real number?
Real numbers are those which can be placed upon a number line stretching to infinity in both directions. To be "not real" you must be unable to do that. We call "not real" numbers "imaginary" numbers. They are numbers which are derived from the square root of -1. If you think about it, what number can be multiplied by itself and you end up with -1. In the real numbers, there isn't one. So we have imaginary numbers. They are written using Euler's notation where i represents the square root of -1. So, to answer your question, i is a "not real" number.
Where do you use negative numbers?
you use negative numbers when measuring the temperature when playing golf or jeopardy! hope this helps! The only place negative numbers work is on paper. It is good when you are having trouble to answer a question.When you need help i would use a number line because it saves getting the answer wrong or even use your fingers because getting the answer wrong is more embarrasing than using your hands/fingers or using a number line...lol
How can you make 150 using only 4 square numbers?
i have two answers: 100+25+16+9=150 16+4+121+9=150
Is negative 14 greater than negative 24?
Yes it is greater. When counting in negative number or using them in math, the smaller the negative number, the bigger it is
