Solving the Math Expression Step-by-Step

To solve the given expression $3[35 + (45 + 10 \div 2 \times 3 - 50) + 5]$, we follow the order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Order of Operations Applied

  • Parentheses/Brackets: Start with the innermost calculations.
    • First, solve the division and multiplication within the inner parentheses: $10 \div 2 \times 3$.
      • Division: $10 \div 2 = 5$.
      • Multiplication: $5 \times 3 = 15$.
      • So, $10 \div 2 \times 3 = 15$.
    • Next, complete the calculation inside the inner parentheses: $(45 + 15 - 50)$.
      • Addition: $45 + 15 = 60$.
      • Subtraction: $60 - 50 = 10$.
      • Thus, $(45 + 10 \div 2 \times 3 - 50) = 10$.
    • Now, substitute this result back into the main bracket: $[35 + 10 + 5]$.
      • Perform the addition: $35 + 10 + 5 = 50$.
  • Multiplication: Finally, multiply the result from the bracket by 3.
    • $3 \times 50 = 150$.

Final Result

The value of the expression $3[35 + (45 + 10 \div 2 \times 3 - 50) + 5]$ is 150.
