| Last one is Division. Division is the same as subtraction because you have to put the bigger number first. | |
| | |
|
|

| But it has the same concept as multiplication because the "groups of" thing is reversed. | |

| | |
| For example, if we did -200 divided by -40 it is going to equal 5 because two negatives equal a positive in any type of a equation. | |
