How does the sign of the product of the positive and a negative number compare withe the sign of the sum of a positive and a negative number?

If you add a positive and a negative number how can you tell whether the answer will be positive negative or equal?
If the negative number is bigger then the answer will be negative If the bigger number is positive then the answer will be positive. All you do is subtract the two numbers and take the sign of the bigger number Ex (+2)+(-7)=(-5)

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.
How do you know if a number will be positive or negative when adding?
Numbers are positive unless they have a minus sign (-) in front of them, in which case they are negative. As for the sum of positive and negative numbers, just add them up and find out. Add the positive, subtract the negative. It's very logical.
Does a negative number minus a positive equal a negative?
