That is a very good question. Let me break it down by Multiplication, Division, Addition, and finally Subtraction.
Multiplication:
Negative x Positive = Negative
Ex: -4 x 5 = -20
Positive x Positive = Positive
Ex: 5 x 4 = 20
Negative x Negative = Positive.
Ex: -5 x -4 = 20
Division:
Negative ÷ Positive = Negative
Ex: -5 ÷ 5 = -1
Positive ÷ Positive = Positive
Ex: 5 ÷ 5 = 1
Negative ÷ Negative = Positive
Ex: -5 ÷ -5 = 1
Addition:
Positive + Positive = Positive
Ex: 20 + 20 = 40
Positive + Negative = Takes the sign of the greater number.
Ex: 50 + -60 = -10
Ex: 60 + -50 = 10
Negative + Negative = Negative
Ex: -50 + -20 = -70
Subtraction:
Positive - Positive = Positive
Ex: 10 - 5 = 5
Negative - Positive = Negative
Ex: -7 - 1 = -8
Negative - Negative = Takes the sign of the greater number
Ex: -5 - (-4) = -1
Ex: -6 - (-7) = 1
Explanation: Remember in Multiplication a Negative x Negative = Positive? Well look at the signs in the last example. In -5 - (-4) the minus sign is being multiplied to the -4. So -1 x -4 = 4. Rewrite it. -5 + 4 = -1. In the second example the sign rule applies. -6 - (-7), Negative x Negative = Positive. So -1 x -7 = 7. Therefore 7 + (-6) = 1.

Is positive divided by negative negative or positive?
Yes, when a positive is divided by a negative, it is negative. ex: 4/-2 would equal -2. It takes two negatives to make a positive in math when you are multiplying or dividing.

you put this in math you idiot
Why does a positive times a negative produces a negative?
Because when there is a positive and a negative in the same problem, it gives you a negative. An easy way to solve problems like that is if there is an odd number of negative signs, then your answer is going to be negative. If there is an even number of negative signs, then your answer is going to be positive. (no matter if there is a positive sign in a math problem).

When you have a negative and positive in math does it become a negative?
It depends on what you do with the negative and positive. If you multiply or divide a positive number and a negative number, then the answer is negative. If you add or subtract a positive number and a negative number, the answer could be negative or positive depending on the numbers involved. If you put a negative sign in front of a positive number, the result is a negative number. If you put a positive sign in front of a negative number (like +(-7)), the result is still negative.
