29 degrees. You can just add 12 and 17 to find this, since the 12 is negative

You need to put the numbers it give you, algo will am I supposed to solve that
When you add a zero to the problem, it shows you are now multiplying in the double-digits. Let's say you are multiplying 12x12. First you cover up the one then multiply them. Then cover up the two and you have 10. When you multiply them, it ends in a zero. Don't think of it as adding a zero but adding to products.
