Editing Negative number (section)

===Subtraction===
As discussed above, it is possible for the subtraction of two non-negative numbers to yield a negative answer:
{{block indent | em = 1.5 | text = {{math|1= 5 − 8  =  −3}} }}
In general, subtraction of a positive number yields the same result as the addition of a negative number of equal magnitude. Thus
{{block indent | em = 1.5 | text = {{math|1= 5 − 8  =  5 + (−8)  =  −3}} }}
and
{{block indent | em = 1.5 | text = {{math|1= (−3) − 5  =  (−3) + (−5)  =  −8}} }}

On the other hand, subtracting a negative number yields the same result as the addition a positive number of equal magnitude. (The idea is that ''losing'' a debt is the same thing as ''gaining'' a credit.) Thus
{{block indent | em = 1.5 | text = {{math|1= 3 − (−5)  =  3 + 5  =  8}} }}
and
{{block indent | em = 1.5 | text = {{math|1= (−5) − (−8)  =  (−5) + 8  =  3}}. }}
