Before scrolling down, take a moment to solve it yourself. Got an answer? Great! Now, let’s explore the common mistakes and find out which answer is truly correct.

Common Mistakes People Make

When faced with problems like this, many people misapply the order of operations, leading to incorrect results. Here are a few errors that frequently occur:

  1. Solving the equation from left to right
    Many assume that math problems should always be solved from left to right, like reading a sentence. However, this approach ignores mathematical rules.
  2. Ignoring the correct order of operations (PEMDAS/BODMAS)
    Some people forget that division and multiplication take priority over addition and subtraction unless parentheses indicate otherwise.
  3. Misplacing operations
    Rushing through calculations often leads to skipping steps or misplacing numbers, resulting in the wrong final answer.

Step-by-Step Solution

To correctly solve this equation, we need to follow PEMDAS (also known as BODMAS):

  • Parentheses
  • Exponents
  • Multiplication & Division (from left to right)
  • Addition & Subtraction (from left to right)

Step 1: Identify the Order of Operations

The given equation is:

8 + 8 ÷ 8 + 8 × 8 – 8

Since there are no parentheses or exponents, we move to multiplication and division first, from left to right.

Step 2: Solve Division and Multiplication First

  • 8 ÷ 8 = 1
  • 8 × 8 = 64

Now, rewrite the equation with these results:

8 + 1 + 64 – 8

Step 3: Solve Addition and Subtraction from Left to Right

  • 8 + 1 = 9
  • 9 + 64 = 73
  • 73 – 8 = 65

Final Answer:

65 (Option a)
