Your question has been specified without parentheses. 10+9*109=991. This is because multiplication occurs first, and addition occurs last before the result may be displayed. This is your question specified by parentheses. (10+9)*109=2071. Using the distributive property, you can multiply 109 with 10 and 9, producing 1090+981. This sums up to 2071. You may also add the inner numbers (adding to 19), and multiply 109 with it, producing 2071.
