What else can I help you with?
When multiplying and dividing rational numbers how do you know if you're into me positive negative?
It the signs of the two numbers that you are multiplying or dividing is the same, then the answer is positive, otherwise the answer is negative. Remember though, that division by 0 is not defined.
Why isn't every integer a whole number?
Integers can be positive, zero or negative. Whole numbers can only be zero or positive. All negative integers are not whole numbers, though they are the additive inverse of a whole number.
How do you use positive numbers in math now?
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.
Why negative numbers don't have logarithim?
The logarithmic function is not defined for zero or negative numbers. Logarithms are the inverse of the exponential function for a positive base. Any exponent of a positive base must be positive. So the range of any exponential function is the positive real line. Consequently the domain of the the inverse function - the logarithm - is the positive real line. That is, logarithms are not defined for zero or negative numbers. (Wait until you get to complex analysis, though!)
How do you multiply a negative number with a positive fraction?
Any negative multplied to a positive is ALWAYS a negative answer, be it an integer or a fraction. Here is a table of multiplication/division of negative/positive numbers. X + = + X - = - X + = - X - = + If no sign is given before the numbers , then read it as positive (+). So (+) a X - b/c = - ab/c . (Note the negative in the answer!!!!!!
Does a negative subtracted from a negative equals in a negative in algebra?
It can. Negative 2 minus negative 1 = negative 1. However, it sometimes might be positive. Negative 5 minus negative 16 = positive 11. If you have two equal negative variables, such as -a - -a, you will get -2a. -2a may still be positive though, if a is a negative number. An example of having two unequal negative numbers is -a - -b, which is -a + b. That may be positive or negative depending on what a and b are equal to.
How many square roots can a positive number have?
Every positive number has two square roots, though the roots are not always whole numbers (or even rational numbers). The more obvious of each numbers roots is the positive one.The positive square root of 4 is 2, because 2*2=4.The positive square root of 5 is roughly 2.236068.The other square root of a number is the negative inverse of their positive root. This is because when two negative numbers are multiplied together the negative signs "cancel out", leaving a positive number.The negative square root of 4 is -2, because -2*-2=4.The negative square root of 5 is roughly -2.236068.Zero has only one square root, itself, and no negative number has any (real number) square roots, since no number multiplied by itself will result in a negative.
Does a positive plus negative equal a negative?
If the positive number is greater than the negative, it's a positive. Ex: 8 + (-3) = 5 If the negative is greater though, then the answer is a negative. Ex: 3 + (-5) = -2
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.
What will be the difference when subtracting two integers with different signs?
Subtracting: Positive - Negative = Positive Negative - Positive = Negative No that is not the way it goes. It is positive+negetive=either counting on which integer is bigger negative+negative=positive positive+positive=positive positive x negetive=negative negative x postitve= negative negative/positive=negative positive/negative=negetive thanks The top is right though because subtracting a negative is like adding so you could never get a negative and subtracting from a positive from negative will always be a negative. The question was for integers with different signs so you don't need to do "positive + positive"
Can your test come out positive then negative?
If it's a pregnancy test the answer is no, A test can come back negative even though its positive. But if it's positive, it's positive 99% of the time.
Is thrifty a positive or negative connotation?
It is positive. --- Actually, it can go either way in modern usage, though it has a better connotation than "stingy."
