===Addition===
[[File:AdditionRules.svg|right|thumb|A visual representation of the addition of positive and negative numbers. Larger balls represent numbers with greater magnitude.]]

Addition of two negative numbers is very similar to addition of two positive numbers. For example,
{{block indent | em = 1.5 | text = {{math|1=(−3) + (−5)  =  −8}}. }}
The idea is that two debts can be combined into a single debt of greater magnitude.

When adding together a mixture of positive and negative numbers, one can think of the negative numbers as positive quantities being subtracted. For example:
{{block indent | em = 1.5 | text = {{math|1=8 + (−3)  =  8 − 3  =  5}} &nbsp;and&nbsp;{{math|1=(−2) + 7  =  7 − 2  =  5}}. }}
In the first example, a credit of {{math|8}} is combined with a debt of {{math|3}}, which yields a total credit of {{math|5}}. If the negative number has greater magnitude, then the result is negative:
{{block indent | em = 1.5 | text = {{math|1=(−8) + 3  =  3 − 8  =  −5}} &nbsp;and&nbsp;{{math|1=2 + (−7)  =  2 − 7  =  −5}}. }}
Here the credit is less than the debt, so the net result is a debt.
