"Do not exceed" in inequality includes this number. Such as not higher than, not greater than, not less than and not less than. , including this number.

Examples are as follows:

The value of x is a positive integer, not exceeding 2, which means that x can take two values: 1 and 2.

Extended data:

Inequalities have three special properties:

(1) Inequality 1: both sides of the inequality add (or subtract) the same number (or formula) at the same time, and the direction of the inequality remains unchanged;

2 Inequality 2: Both sides of the inequality are multiplied (or divided) by the same positive number at the same time, and the direction of the inequality remains unchanged;

3 Inequality 3: Both sides of the inequality are multiplied (or divided) by the same negative number at the same time, and the direction of the inequality changes. ?

Summary: when the product of two positive numbers is constant, their sum has a minimum value; When the sum of two positive numbers is constant, their product has a maximum value.
