divide them or multiply then put a negative because to different signs make a negative to of the same signs make a positive

The value of the quotient of two integers with different signs is the same as if the signs were the same. Because the numbers have different signs, the quotient is negative.

When you are multiplying numbers, if both numbers have the same signs, then the answer is positive; and if the numbers have different signs, the answer is negative. Otherwise, it's just like multiplying two positive numbers.-56 x -8 = 448

Multiply two integers disregarding the signs. Then if the signs are the same, the answer is positive and if the signs are different, the answer is negative. Alternatively, if you are multiplying together a whole bunch of numbers, first find the product while ignoring the signs. Then count all the negative numbers. If the count is even, the answer is positive and if it is odd, the answer is negative.

Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.

Multiplying or dividing a positive and negative gives a negative result. Multiplying or dividing two negatives gives a positive result.

Do you mean with a denominator that is also negative? If you do, then it would be just like dividing positive numbers, the answer would be positive. If you divide two numbers and they have different signs, then the answer will be negative. However the task of dividing is the same no matter what the signs are. So...

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.

You add all the numbers with + signs and subtract all that have minus signs.

positive x positive = positive negative x negative = positive positive x negative = negative negative x positive = negative The same rules apply for dividing, since dividing is actually multiplying by the reciprical.

Then you are adding two rational numbers with different signs! No big deal!
