Find all the possible values of expression :
` ( |x|)/(x) + (|y|)/y `

Explanation

To find all the possible values of the expression \( \frac{|x|}{x} + \frac{|y|}{y} \), we will analyze the expression based on the signs of \( x \) and \( y \).

### Step-by-Step Solution:

1. **Understanding the Absolute Value**:
- The expression \( \frac{|x|}{x} \) can take two values:
- If \( x > 0 \), then \( |x| = x \) and \( \frac{|x|}{x} = 1 \).
- If \( x < 0 \), then \( |x| = -x \) and \( \frac{|x|}{x} = -1 \).
