Hi,
Answer: 13
My work: Order of operations says that multiplication always goes first so you would start off with 10 * 1. After this you would had 10 with 1 and 2 which equals 13. This problem can be easily solved in 2 steps, or with a caculator.
My Numerical work:
Multiply first:
1. 10 *1 =10
Add:
2. 10 + 1 + 2 = 13
I Hoped I Helped!
