Every time you multiply by a negative number, the sign changes, so you have negative, positive, negative, positive... Since the number of negative numbers is odd, the end result is negative.The 2 positive integers don't affect the sign.

Every time you multiply by a negative number, the sign changes, so you have negative, positive, negative, positive... Since the number of negative numbers is odd, the end result is negative. A negative times a positive is always a negative. The rest is the same: just multiply as if they are both positive numbers and then add the negative sign at the end. A negative times a positive is a negative and that negative times a negative would = a positive. So the answer would be a positive number. *&lt;:) 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. Multiplying anything non-zero by a negative number changes the sign. A positive number multiplied by a negative number becomes negative. A negative number multiplied by a negative number becomes positive. You multiply the numbers just like you would normally except that the product will have a negative sign. Example: -6 X 5 = -30. When you multiply a negative number and a positive number, the product will always be negative. Multiplying two positive numbers or two negative numbers will give you positive products. Whenever you multiply two numbers, if they have the same sign, then the answer is positive.When you multiply a number by itself, both numbers in the multiplication obviously have the same sign,so the answer is positive.So there's no number that gives a negative answer when you multiply it by itself.   negative. When you multiply, if there are an odd number of negative signs, the answer is negative. If there are an even number of negative signs, the answer is positive. Or another way to think of this is that two negative signs cancel each other out when multiplying. Due to the sign rules for multiplication, if you multiply several negative numbers, you'll get a result that is alternately negative, positive, negative, positive, etc. The magnitude of the answer is the same whatever the signs of the two numbers. If the two numbers have different signs, then the answer is negative. If they have the same sign, the answer is positive. When you multiply any number by a negative number you reverse its sign. So positive numbers become negative, and negative numbers become positive. That is the meaning of negative multiplication; it is reversal. This is similar to the way that adding a negative number has the same effect as subtracting a positive number. Negative is the opposite of positive. Positive A simple rule to remember this is when multiplying two numbers with the same sign, the result is ALWAYS positive. When multiplying two numbers with different signs, the results is ALWAYS negative. (The product of 33 negative numbers) x (2 positive numbers) = (negative sign) x (positive sign) = negative sign The product of a positive and negative number is always negative The sum of a positive and negative number depends on which one is larger; subtract the two numbers and take the sign of the larger When you multiply two integers of the same sign, the answer is always positive. A positive times a positive is positive and a negative times a negative is positive. the answer is simply by following the rules of multiplication when a negative number is multiplied with a positive number the answer the sign of the product is always negative E.g (2)x(-4)= -8 (-9)x(5)= -45 negative*negative=positive negative/positive=negative negative\negative=positve negative-positive=change the sign to a plus and then change the number after the sign and get your answer negative +positive=which ever numbr is bigger minus positive+positive=positive Multiply the numbers ignoring the signs and then add a negative sign. If ever you have an odd number of negative numbers, the product will always be a negative number. So the answer to this question is negative. Positive + positive = positive Negative + negative = negative Positive + negative will take the sign of the number with the greater absolute value. Think of it this way: It's like spreading the negative sign flu that cancels each other out. positive * positive = positive negative * positive = negative positive * negative = negative negative * negative = positive
