Lets say you have 5 * 5 (five times five). You work things out, and you think it's 25. [ 5 * 5 = 25 ] To check your work, take the solution and divide it by one of the factors you used in the equation. For example: [ 25 / 5 = 5 ] (twenty-five divided-by five equals five) If the statement is true, then your answer is correct.
