To solve the expression $15 - 4 \times 2 + 2$, we follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Step-by-step solution:

1. Perform multiplication first: $4 \times 2 = 8$ So the expression becomes: $15 - 8 + 2$

2. Perform subtraction: $15 - 8 = 7$ So the expression becomes: $7 + 2$

3. Perform addition: $7 + 2 = 9$

Final Answer:

$9$
