Why is a negative number times a positive number always negative?
Take a simple multiplication question such as 2x3It mean that there are 2 groups and these groups each have 3 things in them (or 3 groups each with 2 things)So you add the groups up and get 6Now if you have 2x-3 you have 2 groups and they each have -3 things in them. You add all the negatives 3s up just like you did in the last question and have -6.It is difficult to imagine -3 things or -6 things, so just think of multiplying by a negative will reverse the sign (kind of like reversing the polarity of battery terminals). So if you reverse them one time (negative X positive) then it is opposite of what it was:If the number to be multiplied by is Positive, then the answer is negative : Negative X Positive = Negative.If the number to be multiplied by is Negative, then the answer is positive : Negative X Negative = Positive.If you multiply a number by a positive, it does not reverse the sign: Positive x something equals the a number with the same sign as the something.
If you divide a positive number by a negative number is the answer positive or negative?
Negative. Example: 3/-3= -1
What would be the answer to positive 3 times negative 4?
A positive times a negative is negative, so positive 3 times negative 4 would be negative 12.
What is greater negative 2 o positive 3?
Positive 3 is > 0 while, negative 2 is < 0. So positive 3 > negative 2.
Is the product of 8 negative and 3 positive factors a positive or negative?
If I understand your question correctly, then the answer is negative because if you add positive 3 to negative 8 the answer is negative 5.
Why is a positive times a negative always a negative?
It might be clearer if you think of it this way: Multiplication is repeated addition. 2 x 3 is the same as 3 + 3. They both equal 6. 2 x -3 is the same as -3 + -3. They both equal -6. In the first case, you are increasing the amount of positive things. The answer will be positive. In the second case, you are increasing the amount of negative things. The answer will be negative.

What is negative 9 divided by positive 3?
3
What is square of root 3?
the answer is undefined because a positive and a positive is positive and a negative and a negative is still positive
What is 6 divided by negative 2?
3
A negative plus a positive equels?
A negative or a positive! It depends on the question.EXAMPLES-7 + 3 = -4 ( a negative answer)-7 + 8 = 1 (a positive answer)IF you mean a negative times a positive, the answer is negative:-3 x 5 = -15
What are the rules for multiplying or dividing negative and positive numbers?
Positive x Positive = Positive: 3 x 2 = 6Negative x Negative = Positive: (-2) x (-8) = 16Negative x Positive = Negative: (-3) x 4 = -12Positive x Negative = Negative: 3 x (-4) = -12
