because sometimes you need to subtract #s tht just dont go into each other.
FOR EXAMPLE:::
2 - 4 = -2 or 8 - 12 = -4
Sheri had $2 and wanted a toy costing $4. How much more $ does she need?
2 - 4 = -2 or $2 She needs $2 more
Exponents are negative numbers. This is used in math a lot.
Real numbers are numbers that exist from negative infinity to positive infinity and everything in between. real numbers consist of every number you are used to. Imaginary numbers are numbers that aren't used in conventional math (such as i)
Whole numbers in math are the set of non-negative integers that include zero and all positive integers without any fractions or decimals. This set can be expressed as {0, 1, 2, 3, ...}. Whole numbers do not encompass negative numbers or any numbers that are not whole, such as fractions or irrational numbers. They are used in counting and ordering.
Math class, thermometers.
They are less than 0.
not negative
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.
yes and after you finish your math work on your grammer
In the same way that I have always used them! Positive numbers are used for measures that are greater than zero. They may be whole numbers - such as numbers of people, or words in a question. Or they may be fractional: your height or weight. Remember, though that one person's positive number may be another's negative. If you owe me money, it is a positive asset for me, but a negative one for you. In most cases, negative and positive numbers are used in the same way. There are a very few situations where there seem to be special rules that are applied to negative numbers. But, if you study these from the definition of negative numbers you will see that the rules are really the same, it is just that the numbers are different.
Real numbers are used everywhere. They are used in the work area, at home, and even in fiction. Real numbers, are a part of math, and math is everywhere.
Negative rational numbers are used in the same way that negative whole numbers are used: they are simply the additive inverses of their positive counterparts.
