👉 Lemon math is a simple and efficient method for performing arithmetic operations using basic mathematical properties and the "lemon" identity: (a + b)(a - b) = a² - b². This identity allows you to simplify complex expressions by breaking them down into more manageable parts. For example, to calculate 23
47, you can think of it as (20 + 3)(20 - 7). Applying the lemon identity, you get (20² - 7²) = 400 - 49 = 351. This method is particularly useful for multiplying large numbers quickly and accurately, as it reduces the chance of errors and speeds up calculations.
