Virtually every item sold in a store has a 12-digit UPC barcode which is scanned at the checkout counter. The first 11 digits of a UPC number d1d2d3 ? ? ? d11d12 identify the manufacturer and product. The last digit d12 is a check digit which is chosen so that 3d1+d2+3d3+d4+3d5+d6+3d7+d8+3d9+d10+3d11+d12 =0 pmod10q.
If the congruence does not hold, an error has been made and the item must be scanned again, or the UPC code enteblack by hand. Which of the following UPC numbers were scanned incorrectly?
1-33732000625
2-040293673034

Contrary to a popular belief, equation in math also contains things like inequalities and expressions that require logic and verbal explanations. This is where equation help becomes useful as you look at the answers below. See equation problems submitted by students like you and explore the answers. It will help you to understand the logic as you approach equation algebra and study expressions examples. These are not as complex as they may seem once you learn how to connect expressions and equations and understand them as a finite combination of symbols, depending on use.
