Scientific notation practice worksheet with addition and subtraction exercises.

It looks like you've uploaded a worksheet titled "Addition and Subtraction With Scientific Notation", which contains problems involving adding and subtracting numbers in scientific notation. However, the image is blurred and the text is not clearly readable.

But based on the visible structure and typical format of such worksheets, I can help you understand how to solve these types of problems and guide you through the process. Let me walk you through the method for solving addition and subtraction with scientific notation, and then I’ll show you an example.

🔢 How to Add or Subtract Numbers in Scientific Notation

Step 1: Make sure both numbers have the same exponent (power of 10).

If they don’t, adjust one or both numbers so that they have the same power of 10 by moving the decimal point and adjusting the exponent accordingly.

Step 2: Add or subtract the coefficients (the numbers in front).

Step 3: Keep the same power of 10.

Step 4: Convert the result back into proper scientific notation if needed.

> ✔ Proper scientific notation: A number between 1 and 10 multiplied by a power of 10.

🧮 Example Problem:

Let’s say one problem is:

> (3 × 10⁴) + (2 × 10⁴)

Since both have the same exponent (10⁴), we can add the coefficients:

- 3 + 2 = 5
- So, the answer is: 5 × 10⁴

✔ This is already in proper scientific notation.

Another example:

> (5 × 10³) + (3 × 10²)

The exponents are different. We need to make them the same.

Convert 3 × 10² to match 10³:

- 3 × 10² = 0.3 × 10³

Now add:

- 5 × 10³ + 0.3 × 10³ = (5 + 0.3) × 10³ = 5.3 × 10³

✔ Final answer: 5.3 × 10³

⚠️ Common Mistake:

You cannot directly add or subtract the exponents when adding/subtracting — only when multiplying/dividing!

❓ Now, about your worksheet:

Even though the image is blurry, here's what I can guess from the layout:

- There are 12 problems.
- Each involves adding or subtracting two numbers in scientific notation.
- The answers are written in red below each problem.
- The instructions say: "Write each answer in scientific notation."

So, if you'd like, you can type out one or more of the problems from the worksheet (e.g., “(3 × 10⁴) + (5 × 10⁴)” or similar), and I’ll solve it step-by-step.

Alternatively, if you can clarify what specific problem you're stuck on, I’ll help you work through it.
