Brain Test Level 339
Level 339 Solution
The question asks you to calculate the result of the equation: 7 + 7 / 7 + 7 * 7 - 7.
You must 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).
- First, perform Division and Multiplication: 7 / 7 = 1, and 7 * 7 = 49.
- The equation simplifies to: 7 + 1 + 49 - 7.
- Now, perform Addition and Subtraction from left to right: 8 + 49 - 7 = 57 - 7 = 50.
The correct answer is 50.
