1. **Problem Statement:** Use the numbers 1.45 and 1.14 in a mathematical context. Since the user did not specify an operation, let's explore basic operations: addition, subtraction, multiplication, and division. 2. **Formulas and Rules:** - Addition: $a + b$ - Subtraction: $a - b$ - Multiplication: $a \times b$ - Division: $\frac{a}{b}$ (where $b \neq 0$) 3. **Calculations:** - Addition: $1.45 + 1.14 = 2.59$ - Subtraction: $1.45 - 1.14 = 0.31$ - Multiplication: $1.45 \times 1.14 = 1.653$ - Division: $\frac{1.45}{1.14} \approx 1.2719$ 4. **Explanation:** - Addition combines the two numbers to get their total. - Subtraction finds the difference between the two numbers. - Multiplication calculates the product. - Division finds how many times the second number fits into the first. These operations are fundamental in algebra and arithmetic, useful for various applications.
