Here’s a viral math puzzle making the rounds:
7 × 7 – 7 ÷ 7 + 7 = 55
At first glance, it seems simple, but it’s a tricky one that requires you to apply the correct order of operations (PEMDAS/BODMAS). Think you can solve it in 10 seconds? Let’s break it down:
- 7 × 7 = 49 (First, multiplication)
- 49 – 7 ÷ 7 = 48 (Then, division)
- 48 + 7 = 55 (Finally, addition)
And there you have it—the correct answer is 55!
