In math, "equal to" is a fundamental concept that represents the relationship between two quantities that have the same value. The symbol used to denote equality is the equals sign (=).
If we have the equation 5 + 3 = 8, it means that the sum of 5 and 3 is equal to 8. The equals sign indicates that the value on the left side of the equation is the same as the value on the right side.
