Question 303733
If n is a negative number, then {{{n<0}}}. Now multiply both sides by -1 to get {{{-n>0}}} (notice the sign change). Now simply add two to both sides to get {{{2-n>2}}}. Since {{{2-n>2}}}, this means that {{{2-n}}} is definitely greater than zero. So {{{2-n}}} is positive for all negative values of 'n'.
