### Easiest Way to Learn Multiplication of Integers

Now that we are done with the addition, and subtraction of integers, let’s move on to the multiplication of integers. This is the same as the conventional method of multiplication of numbers, but there is one twist. As integers involve negative numbers along with positive numbers along with positive numbers, we have to take the signs that they carry into consideration during operations. So what can we do? We can multiply to positive integers, we can multiply to negative integers or we can multiply one positive and one negative integer. So to help you make sense out of all of this, let me introduce you to a couple of characters. The angel and the Devil. The angel is obviously good, therefore represents the positive side and the Devil represents the negative side. Now these guys are going to help me explain multiplication to you through a story. So you can thank them after this. Ok. Let’s consider heaven, the hometown of the angel. Everyone is impressed with the angel, trusts him, and then decide to have him in-charge of heaven and its inhabitance. Something good has happened to someone good. Basically, this outcome is considered positive. Agree with me, Right? This means that positive multiplied by positive will give you a positive output. Sometimes later, the devil sends his men to infiltrate heaven and brainwash everyone into believing that the angel is actually not good enough to handle the whole place. Eventually the angel’s creditability gets questioned and the responsibility of protecting heaven is taken away from him. So something bad has happened to someone good and obviously is supremely bad. This means that when a positive integer is multiplied with a negative integer, the output is negative. Right now the devil’s happiness knows no bounce. He is enjoying the angel’s bad luck and hardships. Poor angel! With the angel, out of picture the devil eventually takes absolute control of heaven. In this situation, when devil commands heaven’s people, something bad has happen to someone good. Same as this, if I multiply a negative integer with a positive integer, the output would be negative. So now, what’s going to happen when devil is in-charge of heaven? Because so much trouble, wrecks absolute havoc all over the place, it’s a big mess. This makes good people of heaven to come to the senses; they go against them and throw him out of heaven. So here something bad has happened to someone bad. But the final outcome is awesome. It’s good. Again in integers, a negative integer multiplied with another negative integer is going to give you…yes, a positive integer. And then let’s end the story. The angel comes back, takes control again, and everybody lives happily ever after. So now let me explain these concepts without the angel and the devil.
