An inequality compares two values, and a variable such as xxx or nnn stands for a number. A solution is any value that makes the inequality true.

Read the sign from left to right. For example, x<4x < 4x<4 means less than 4, x>4x > 4x>4 means greater than 4, x≤4x \le 4x≤4 means less than or equal to 4, and x≥4x \ge 4x≥4 means greater than or equal to 4.

The extra line in ≤\le≤ or ≥\ge≥ means the end value is included. Without that line, the end value is not included.
