Let two negative numbers be -a and -b. For example : -2 and -5.

Let us consider the rules for individual arithmatic operations:

Addition of 2 negatuve numbers:

-a+(-b): negative

e.g, -2+(-5)=-7

Substraction of 2 negative numbers:

(-a)-(-b) is negtive if |a|>|b| and positive therwise.

e.g, (-2)-(-5)=-2+5=3 (positive) as |-2|

Multiplication of 2 negative numbers:

(-a)*(-b)=ab: positive

e.g., (-2)*(-5)=10

Division of 2 negative numbers:

\(\displaystyle-\frac{{a}}{{-{{b}}}}\): positive

e.g, \(\displaystyle-\frac{{2}}{{-{{5}}}}={0.40}\)
