Step-by-step explanation:
You also have to pay attention to the signs when you multiply and divide. There are two simple rules to remember:
When you multiply a negative number by a positive number then the product is always negative.
When you multiply two negative numbers or two positive numbers then the product is always positive.
This is similar to the rule for adding and subtracting: two minus signs become a plus, while a plus and a minus become a minus. In multiplication and division, however, you calculate the result as if there were no minus signs and then look at the signs to determine whether your result is positive or negative. Two quick multiplication examples:
3⋅(−4)=−12
3 times 4 equals 12. Since there is one positive and one negative number, the product is negative 12.
(−3)⋅(−4)=12
