Hi, so before I start: PRODUCT = Multiplication and SUM = Addition. In other words, you are saying: The multiplication of 6 and the addition of 3 and 20. Lets start with 3 and 20. In other words it is 3+20 which is equal to =23. Now considering you only have one number for the product, I'm presuming you mean the product of 23 and 6. In that case, 23 x 6 = 138
