Calculating a series of numbers with a mix of integers and decimals, like 2.4, 5.5, 8.3, and 8.8, can be straightforward if you follow basic arithmetic operations. The first step is to understand what mathematical operation you want to perform on these numbers. Assuming you want to find the sum, average, or possibly perform a more complex calculation involving these numbers, let's break down the steps for each scenario.
Sum Calculation
To calculate the sum of these numbers, you simply add them together. The operation would look like this: 2.4 + 5.5 + 8.3 + 8.8. Performing the addition:
1. Start with 2.4 + 5.5 = 7.9
2. Then, add 8.3 to that result: 7.9 + 8.3 = 16.2
3. Finally, add 8.8 to the last result: 16.2 + 8.8 = 25
The sum of 2.4, 5.5, 8.3, and 8.8 is 25.
Average Calculation
Calculating the average involves summing all the numbers and then dividing by the count of the numbers. From the previous step, we know the sum is 25. Since there are 4 numbers:
1. Sum of the numbers: 25
2. Count of the numbers: 4
3. Average = Sum / Count = 25 / 4 = 6.25
The average of 2.4, 5.5, 8.3, and 8.8 is 6.25.
| Operation | Result |
|---|---|
| Sum | 25 |
| Average | 6.25 |
More Complex Calculations
If you’re looking to perform more complex operations, such as multiplication, division, or a combination of operations, the approach will differ. For instance, if you want to calculate the product of these numbers:
1. Start with 2.4 * 5.5 = 13.2
2. Then, multiply that result by 8.3: 13.2 * 8.3 = 109.56
3. Finally, multiply by 8.8: 109.56 * 8.8 = 963.648
The product of 2.4, 5.5, 8.3, and 8.8 is 963.648.
Combination of Operations
In cases where you need to perform a combination of addition, subtraction, multiplication, and division, following the order of operations (often remembered by the acronym PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division from left to right, Addition and Subtraction from left to right) is crucial.
For example, calculating (2.4 + 5.5) * (8.3 - 8.8):
1. Inside the parentheses first: 2.4 + 5.5 = 7.9 and 8.3 - 8.8 = -0.5
2. Then, multiply the results: 7.9 * -0.5 = -3.95
The result of (2.4 + 5.5) * (8.3 - 8.8) is -3.95.
| Operation | Result |
|---|---|
| Product | 963.648 |
| Combination Example | -3.95 |
