The correct answer is 7.
Using the standard order of operations (BODMAS/PEMDAS), which dictates that multiplication must be performed before addition:
Multiply first: 2×3 = 6
Add second: 1 + 6 = 7
If you added first (1 + 2 = 3) and then multiplied (3×3 = 9), you would get 9, but that is mathematically incorrect.
