Simplify Mathematical Expression

Step-by-Step Solution

The expression to simplify is: $5 + 2 \times 3 \div (3 \times 2) \times 3$

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).

  1. Parentheses: Calculate the expression inside the parentheses first.

    $(3 \times 2) = 6$

    The expression becomes: $5 + 2 \times 3 \div 6 \times 3$

  2. Multiplication and Division (left to right): Perform multiplications and divisions from left to right.
    • First, calculate $2 \times 3$:

      $2 \times 3 = 6$

      The expression is now: $5 + 6 \div 6 \times 3$

    • Next, calculate $6 \div 6$:

      $6 \div 6 = 1$

      The expression is now: $5 + 1 \times 3$

    • Finally, calculate $1 \times 3$:

      $1 \times 3 = 3$

      The expression is now: $5 + 3$

  3. Addition: Perform the final addition.

    $5 + 3 = 8$

The simplified value of the expression is 8.
