Solving the Equation: 125 + 90 - 5

This article will guide you through solving the simple arithmetic equation: 125 + 90 - 5. We'll break down the process step-by-step, explaining the order of operations and the logic behind the solution. This seemingly straightforward problem is a great example of how understanding basic mathematical principles can lead to accurate results.

Understanding the Order of Operations (PEMDAS/BODMAS)

Before we begin, it's crucial to understand the order of operations. This is a set of rules that dictates the sequence in which we perform calculations. These rules are often remembered using the acronyms PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction). Both acronyms represent the same order of operations.

In this equation, we only have addition and subtraction. According to PEMDAS/BODMAS, we perform these operations from left to right.

Step-by-Step Solution

1. Addition: First, we add 125 and 90:

   125 + 90 = 215

2. Subtraction: Next, we subtract 5 from the result:

   215 - 5 = 210

Therefore, the solution to the equation 125 + 90 - 5 is $\boxed{210}$.

Practical Applications

Understanding basic arithmetic like this is fundamental to many aspects of life. From balancing your checkbook to calculating discounts in a store, the ability to perform simple calculations accurately is essential for everyday problem-solving.

Beyond the Basics

While this equation is simple, the principles involved apply to more complex mathematical problems. Mastering the order of operations is key to tackling more advanced equations involving parentheses, exponents, and other mathematical functions.

Conclusion

Solving 125 + 90 - 5 demonstrates the importance of following the order of operations. By systematically working through the equation from left to right, following the rules of PEMDAS/BODMAS, we arrive at the correct answer of 210. This seemingly simple equation highlights the fundamental principles of arithmetic and their relevance in our daily lives. Remember, a solid grasp of basic math provides a strong foundation for more advanced mathematical concepts.
