162 ÷ [51 − {29 − (9 − \(\overline{6+7}\))}] =?
To solve this problem, we need to follow the order of operations, often remembered by the acronym BODMAS/PEMDAS. This means we perform operations in the following order: Brackets (or Parentheses), Orders (or Exponents), Division and Multiplication (from left to right), and Addition and Subtraction (from left to right). The vinculum (bar over numbers) acts as a grouping symbol, similar to parentheses.
First, evaluate the expression under the vinculum (bar):
\[ 6 + 7 = 13 \]Substitute this value back into the original expression:
\[ 162 \div [51 - \{29 - (9 - 13)\}] \]Next, evaluate the innermost parentheses:
\[ 9 - 13 = -4 \]Substitute this value back:
\[ 162 \div [51 - \{29 - (-4)\}] \]Simplify the expression inside the curly braces. Remember that subtracting a negative number is equivalent to adding a positive number:
\[ 29 - (-4) = 29 + 4 = 33 \]Substitute this value back:
\[ 162 \div [51 - 33] \]Now, evaluate the expression inside the square brackets:
\[ 51 - 33 = 18 \]Finally, perform the division:
\[ 162 \div 18 = 9 \]D) 9 is the correct answer after following the order of operations.
