If you multiply together two numbers with the same sign (i.e. two positives or two negatives) then your answer will always be a positive number.
For example, 2 * 2 = 4 and -2 * -2 = 4.
When multiplying numbers, the rules for signs are straightforward: the product of two positive numbers is positive, and the product of two negative numbers is also positive. However, when multiplying a positive number by a negative number, the result is negative. In summary, multiplying numbers with the same sign yields a positive result, while multiplying numbers with different signs results in a negative product.

Temporarily ignore the signs and multiply or divide as usualIf signs of the two numbers to be multiplied or divided, add + sign to your answer. If signs are different, add - ( minus) to your answer.+ signs are optional-- a number without a sign is assumed to be positive.
You simply add the numbers: the answer has a positive sign.
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.
If there are an odd number of numbers with a negative sign then the sign of the product is negative. Otherwise it is positive.

It changes because two negatives make a positive!!!!!!!!!!!!
When multiplying integers, multiplying by the same sign will always produce a positive integer. Such as a negative times a negative equals a positive. If the signs are different then the product will be a negative.
you add all numbers and you keep the sign of the bigger number -9
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.
