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.
