What does of mean in a math equation?Answer: In Algebra, ‘of’ means to multiply. Let’s see some examples. Explanation: In math, ‘of’ is also considered as one of the arithmetic operations which means multiplication within the brackets. For example, we need to find one-third of 30. Mathematically, we re-write it as 1/3 of 30 = 1/3 × 30 = 10.
