võrdustunnus

Võrdustunnus is the Estonian term for the equality sign, represented by the symbol "=". It is a fundamental symbol in mathematics and logic, used to indicate that two expressions or quantities are equal in value. The võrdustunnus is placed between two sides of an equation, signifying that the expression on the left has the same value as the expression on the right. For example, in the equation 2 + 3 = 5, the võrdustunnus shows that the sum of 2 and 3 is equivalent to the number 5.

The concept of equality is crucial for algebraic manipulation, problem-solving, and defining relationships between numbers and variables. When a võrdustunnus is used, it asserts a statement of equivalence. If the statement is true, the equation is considered true. If the values on either side are different, the equation is false. The võrdustunnus is a cornerstone of mathematical notation and is universally understood across different languages and cultures in its symbolic form.
