Any division problem is actually a multiplication problem:
-
6÷2=3 because 2⋅3=6.
-
6÷-2=-3 because -2⋅-3=6.
-
-6÷2=-3 because 2⋅-3=-6.
-
-6÷-2=3 because -2⋅3=-6.
Because we know how to multiply signed numbers, that means we know how to divide them.
- A positive number divided by a negative number always results in a negative number.
- A negative number divided by a positive number always results in a negative number.
- A negative number divided by a negative number always results in a positive number.
A number that can be used in place of the variable that makes the equation true is called a solution to the equation. For example, for the equation x÷-2=5, the solution is -10 because it is true that -10÷-2=5.
