What do negative numbers represent in real world situations?
Loss or negative growth, mostly in economic matters temperature
What is a system for solving problems using letters to represent numbers?
It is algebra.
What do imaginary numbers represent?
The real numbers together with the imaginary numbers form a sort of vector. What these complex numbers (complex means the combination of real and imaginary numbers) represent depends on the specific situation. Just as there are situations where it doesn't make sense to use negative numbers, or fractional numbers, in many common situations it doesn't make sense to use complex numbers. In an electrical circuit (specifically, AC), the real numbers might represent resistance, while the imaginary number represent reactance - and voltages and currents are also represented by complex numbers, with the angle of the complex number representing how much one quantity is ahead or behind another quantity (the "phase angle"). In quantum mechanics, the complex numbers might not represent anything (perhaps they don't, I am not sure...), but they are useful for calculations.
Is there a number that doesn't have a square root?
Any negative number, and infinity. However, a number (called "i") was created to represent the square roots of negative numbers.
HOW TO write integers that can be used to represent the situation like a debit of 60?
If you use positive numbers to represent money which you have or are owed (credit), then use negative numbers to represent debits.Remember, though, that sometimes the choice of which of the two is positive is arbitrary and depends on you. If I owe you money, the situation would be represented by a negative number in my accounts but a positive entry in yours.
Why do you use negative numbers in Math?
You use negative numbers to represent subtractions (10-5 is same as 10 + -5) Also, you use these to represent things that can be negative.

What is a system for solving problems using letters to represent numbers?
It is algebra.
Is a star with magnitude -1 the brightest?
Lower magnitude numbers are brighter; negative numbers represent brighter objects than positive numbers.
What happens when you use the Sum function and in the range of cells you find negative numbers?
It will still perform the calculation. The SUM function can deal with positive and negative numbers and it will deal with negative numbers correctly. So there will be no problems or errors if there are negative numbers amongst the numbers in the range of cells that it is calculating.
What is the difference between red and black numbers?
The color. red numbers usually represent negative as seen in bank accounts
How do you use negative numbers during everyday life?
Negative numbers are often found in measurements. They are used to represent numbers that have sunk below 0 (ex: temperature, debt) or have become the inverse of a number (velocity, energy, negative exponents). Without machines of sorts negative numbers are very rare in everyday life, but so are very large numbers or very small numbers.

How do you do a math problem?
Math problemsThis page is used to construct a set of simple arithmetic problems. You can choose the number of problems presented, as well as the types of questions asked. Fill in all of the boxes and then hit the Submit button to generate the problems. Once generated you can print the sheet out for work offline, or you can answer the problems on the computer and have the results graded.AdditionDo you want addition questions?Can numbers to be added be negative?Can results be negative?How many addition problems do you want?How large can the numbers be?

The following parameters allow you to change the presentation. The default values make is easy for a child to write on the page. Choosing a smaller font size and more problems per line allow more problems to be put onto a printed page. You can enter silly combinations. If you do that, you will get silly output.Font size:Problems per lineThis is will help you with your question. Just remember the simple questions. Do i need to subtract, multiply, divide, or add. Remember also if your doing more advance. What is may goal? Do i need to get "X" alone or "Y" alone.My source (web page) is http://www.armoredpenguin.com/math

Why do negative numbers exist?
Negative numbers exisit because negative numbers are useful to describe values on a scale below zero (0), such as temperature and also book kepping where they can be used to represent credits
