On Thursday 31st January, Samantha had assigned us to research one of the topics that related to Pre-algebra course in Khan Academy. After we choose our topic, we have to teach that topic to our teams. I was really interested in a topic related to adding a negative number.
When we add negative numbers and negative numbers together, the number won’t get a bigger number, but the number is started to decrease as we add a negative number together. Let’s say that we start the number from Zero. When we talk about positive numbers, it will go to the right count from Zero and a negative number will go to the left from Zero. If we add a negative number together just like we have negative 2 plus with negative 2 it will become negative 4. We already have negative 2 that count from Zero to the left and if we add another negative 2 which mean that we have added two number to the left and it will become negative 4.
