The 5-5x5+5 Solution: A Math Riddle Explained
The 5-5x5+5 solution is a math riddle that has been circulating on social media and has left many people scratching their heads. The equation seems simple, but the answer is not as straightforward as it appears. In this article, we will break down the solution and provide a step-by-step explanation.
The Equation:
The equation is:
5 - 5x5 + 5
Step-by-Step Solution:
To solve this equation, we need to follow the order of operations (PEMDAS):
- Parentheses: None
- Exponents: None
- Multiplication and Division (from left to right): 5x5 = 25
- Addition and Subtraction (from left to right): 5 - 25 + 5
Now, let's calculate the equation:
