Give me an example of add and subtract with scientific notation then show ur work
17 days ago
Sure! Let's go through examples of both addition and subtraction using scientific notation.
### Example 1: Addition
**Problem: \( 2.5 \times 10^3 + 3.1 \times 10^2 \)**
**Step 1: Adjust to the same power of 10.**
To add these two numbers, we should express them with the same exponent. The second number, \( 3.1 \times 10^2 \), can be rewritten as:
\[
3.1 \times 10^2 = 0.31 \times 10^3
\]
**Step 2: Now, add the coefficients.**
Now we can add them:
\[
2.5 \times 10^3 + 0.31 \times 10^3 = (2.5 + 0.31) \times 10^3 = 2.81 \times 10^3
\]
### Result:
\[
2.5 \times 10^3 + 3.1 \times 10^2 = 2.81 \times 10^3
\]
---
### Example 2: Subtraction
**Problem: \( 5.4 \times 10^4 - 2.1 \times 10^3 \)**
**Step 1: Adjust to the same power of 10.**
We can convert \( 2.1 \times 10^3 \) to have the same exponent as \( 5.4 \times 10^4 \):
\[
2.1 \times 10^3 = 0.21 \times 10^4
\]
**Step 2: Now, subtract the coefficients.**
Now we perform the subtraction:
\[
5.4 \times 10^4 - 0.21 \times 10^4 = (5.4 - 0.21) \times 10^4 = 5.19 \times 10^4
\]
### Result:
\[
5.4 \times 10^4 - 2.1 \times 10^3 = 5.19 \times 10^4
\]

Can u make it more human

Absolutely! Let’s go through the addition and subtraction with scientific notation in a more conversational style.
### Example 1: Addition
**Problem: What’s \( 2.5 \times 10^3 + 3.1 \times 10^2 \)?**
1. **First, let's align the terms.**
We see that \( 2.5 \times 10^3 \) is in the thousands, but \( 3.1 \times 10^2 \) is only in the hundreds. To make it easier to add, we can convert \( 3.1 \times 10^2 \) into the same power of ten as the first term.
So, we rewrite \( 3.1 \times 10^2 \) as \( 0.31 \times 10^3 \).
2. **Now, let’s add.**
With both terms now in terms of \( 10^3 \), we can add the coefficients:
\[
2.5 + 0.31 = 2.81
\]
3. **Putting it together,** we have:
\[
2.5 \times 10^3 + 3.1 \times 10^2 = 2.81 \times 10^3
\]
### Example 2: Subtraction
**Problem: How about \( 5.4 \times 10^4 - 2.1 \times 10^3 \)?**
1. **Align the terms again.**
Here, \( 5.4 \times 10^4 \) is in the tens of thousands, while \( 2.1 \times 10^3 \) is only in the thousands. So, let’s convert \( 2.1 \times 10^3 \) to match the power of ten of the first number:
We can rewrite it as \( 0.21 \times 10^4 \).
2. **Now, it’s time to subtract.**
With both terms in terms of \( 10^4 \), we can perform the subtraction:
\[
5.4 - 0.21 = 5.19
\]
3. **So, our final answer is:**
\[
5.4 \times 10^4 - 2.1 \times 10^3 = 5.19 \times 10^4
\]
### Summary
- **For addition:** \( 2.5 \times 10^3 + 3.1 \times 10^2 = 2.81 \times 10^3 \)
- **For subtraction:** \( 5.4 \times 10^4 - 2.1 \times 10^3 = 5.19 \times 10^4 \)
I hope this makes it clearer! If you have any more questions or need further explanation, just let me know!

Make it more shorter

Sure! Here’s a shorter version of the addition and subtraction in scientific notation:
### Example 1: Addition
**Problem:** \( 2.5 \times 10^3 + 3.1 \times 10^2 \)
1. **Convert:** Rewrite \( 3.1 \times 10^2 \) as \( 0.31 \times 10^3 \).
2. **Add:**
\[
2.5 + 0.31 = 2.81
\]
3. **Result:**
\[
2.5 \times 10^3 + 3.1 \times 10^2 = 2.81 \times 10^3
\]
---
### Example 2: Subtraction
**Problem:** \( 5.4 \times 10^4 - 2.1 \times 10^3 \)
1. **Convert:** Rewrite \( 2.1 \times 10^3 \) as \( 0.21 \times 10^4 \).
2. **Subtract:**
\[
5.4 - 0.21 = 5.19
\]
3. **Result:**
\[
5.4 \times 10^4 - 2.1 \times 10^3 = 5.19 \times 10^4
\]

Noooo its add and subtract in scientific notation. Not addition and subtraction
17 days ago
Got it! Let’s do an example of addition and subtraction using numbers already in scientific notation.
### Example 1: Addition in Scientific Notation
**Problem:** \( (3.0 \times 10^4) + (4.5 \times 10^4) \)
1. **Add the coefficients:**
\[
3.0 + 4.5 = 7.5
\]
2. **Keep the exponent the same:**
\[
= 7.5 \times 10^4
\]
**Result:**
\[
(3.0 \times 10^4) + (4.5 \times 10^4) = 7.5 \times 10^4
\]
---
### Example 2: Subtraction in Scientific Notation
**Problem:** \( (6.0 \times 10^5) - (2.2 \times 10^5) \)
1. **Subtract the coefficients:**
\[
6.0 - 2.2 = 3.8
\]
2. **Keep the exponent the same:**
\[
= 3.8 \times 10^5
\]
**Result:**
\[
(6.0 \times 10^5) - (2.2 \times 10^5) = 3.8 \times 10^5
\]
