If abc is a nonzero rational number, find the value of a/│a│+b/│b│+c/│c│ If abc is a non-zero rational, find the value of a/│a│+b/│b│+c/│c│

If abc is a nonzero rational number, find the value of a/│a│+b/│b│+c/│c│ If abc is a non-zero rational, find the value of a/│a│+b/│b│+c/│c│

Discussion by case... Because abc is a non-zero rational number, a, b and c are all non-zero rational numbers. When all three numbers are negative, the answer is -1+(-1)+(-1)=-3. When two of the three numbers are negative, the answer is -1+(-1)+1=-1. When one is negative, the answer is -1+1+1=1. When there is no negative, the answer is 1+1+1=3.

There are only four kinds of cases. Of the three numbers, there is only one positive number, two positive numbers, three positive numbers, and three negative numbers. Try them one by one.
