Numbers: Negative numbers
Dividing negative numbers
Since we can write a division as a product, we can use the same calculation rules for multiplication of negative numbers, for division.
We can write a division as a product with a fraction. In the chapter about fractions we will elaborate on this. This results in:
\[\begin{array}{rcrcrcrcr}\green6&:&\green2&=&\green6 &\times& \green{\frac{1}{2}}&=&\green3 \\ \green6&:&\blue{2}&=&\green6 &\times& \blue{\frac{1}{2}}&=&\blue{3} \\ \blue{6}&:&\green2&=&\blue{6} &\times& \green{\frac{1}{2}}&=&\blue{3} \\ \blue{6}&:&\blue{2}&=&\blue{6} &\times& \blue{\frac{1}{2}}&=&\green3 \end{array}\]
Using this example, we can state the general calculation rules for division.
The calculation rules for division of positive and negative numbers are: \[\begin{array}{rclll} 
Examples \[\begin{array}{rrrrr} \\[1pt]

We divide two positive numbers by each other, so the result is positive.
