Solving 0.5 x 7 x 4
This article will guide you through solving the simple multiplication problem 0.5 x 7 x 4. While this equation may seem straightforward, it's a great opportunity to explore the order of operations and understand how decimals work in multiplication.
Order of Operations
In mathematics, the order of operations is crucial for achieving the correct answer. We use the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to remember the order. Since we only have multiplication in this equation, we can simply multiply from left to right.
Step-by-Step Solution
- 0.5 x 7: Multiplying 0.5 by 7 gives us 3.5.
- 3.5 x 4: Multiplying 3.5 by 4 gives us 14.
Therefore, 0.5 x 7 x 4 = 14
Key Takeaways
- Understanding the order of operations is crucial in solving mathematical equations.
- Multiplying decimals by whole numbers is a straightforward process.
- Always double-check your calculations to ensure accuracy.
Let's explore some additional applications of this problem:
- Real-world application: You could use this calculation to determine the total cost of buying 7 items for $0.50 each, with a discount of 4 times the original price.
- Further exploration: You could explore how the answer changes if we rearrange the order of the numbers. For example, 4 x 7 x 0.5 still equals 14.
By understanding basic mathematical principles and practicing simple calculations, you can build a strong foundation for more complex mathematical concepts.
