For any mathematical expression follow the BODMAS rule which states that we should calculate the Brackets first (2 + 4 = 6), then the Orders (52 = 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).
Step-by-step explanation:
(5+4) × 5 + 3.3
Bracket open = 9
Since there is no division, so multiply 9×5, which is 45
