If you love a good arithmetic brain teaser, this one’s for you. It’s time to flex those brain muscles and tackle a classic order of operations PEMDAS puzzle.
The Ultimate Mental Math Test: Can You Solve It?
Here’s the equation we’re challenging you with today. Remember, no calculators allowed! Grab a pen and paper, or simply use your incredible mental power.
8 × 4 + 20 ÷ 5 = ?
Think you know the answer? Consider these options, but remember to rely on your own calculations!
- A) 13
- B) 20
- C) 28
- D) 25
Understanding PEMDAS: The Key to Cracking the Code
Before you jump to conclusions, let’s refresh our memory on the golden rule of mathematics: the Order of Operations, often remembered by the acronym PEMDAS (or BODMAS in some regions). It stands for:
- Parentheses (or Brackets)
- Exponents (or Orders)
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Following this order ensures everyone arrives at the same correct answer for any given mathematical expression. It’s crucial for solving our current PEMDAS puzzle!
Let’s Solve It! Step-by-Step Calculation
Time to apply PEMDAS to our challenge: 8 × 4 + 20 ÷ 5 = ?
Step 1: Tackle Multiplication and Division
According to PEMDAS, multiplication and division come before addition. We work from left to right for these operations.
- First, let’s solve the multiplication: 8 × 4 = 32
- Next, we perform the division: 20 ÷ 5 = 4
Now, our equation looks much simpler: 32 + 4 = ?
Step 2: Perform Addition
With only addition left, this is the final step.
- 32 + 4 = 36
The Correct Answer Revealed
Using the standard order of operations, PEMDAS, the unique and mathematically correct answer to the equation 8 × 4 + 20 ÷ 5 is 36.
Did you get 36? If so, amazing job! You’ve mastered the order of operations and crushed this mental math test. If your answer was different, don’t worry! This is a common arithmetic brain teaser designed to check how well we remember foundational math rules. The provided options can sometimes be distractors based on common calculation errors, but the PEMDAS rule always guides us to the definitive solution.
