two non zero numbers : m & n
m + n =0
1) m & n are odd - Never true
[tex]m+n>0[/tex]2) m & n are positive - never true
[tex]_{(+m)\text{ + (+n)>}0}[/tex]3) m and are negative- never true
[tex](-m)\text{ + (-n)=-m-n<}0[/tex]4) Im is equal to Inl.- Always true
[tex]\begin{gathered} |m|=\pm m,\text{ |n|=}\pm n \\ so,\text{ +m-n=0 or -m+n=0} \end{gathered}[/tex]5) |m| is not equal to |n|- Never true
[tex]\begin{gathered} |m|\text{ and |n| are not equal.} \\ So\text{ during summation they will show a poistive number} \end{gathered}[/tex]6) m is positive and n is negative. - Sometimes true
If m is equal to n then:
+m + (-n) = m-n =0
