i need to multiply some number and add to r3
answer quick!
To multiply a number and add it to row 3, you will need to perform the following steps:
1. Choose the number you want to multiply.
2. Multiply the chosen number by each value in row 3 (the values in columns x, y, and z).
3. Add the products obtained in step 2 to the corresponding values in row 3 (the rhs column).
4. Write down the new values obtained for row 3 after performing the multiplication and addition.
Here's an example calculation using the given values:
Let's say you want to multiply the number 2 and add it to row 3. Follow these steps:
1. Multiply 2 by each value in row 3:
- 2 * 0 = 0
- 2 * 3 = 6
- 2 * 4 = 8
2. Add the products obtained to the corresponding values in row 3:
- 0 + 0 = 0
- 3 + 6 = 9
- 4 + 8 = 12
3. Write down the new values obtained for row 3 after the multiplication and addition:
- Row 3: 0, 3, 4, 12
So, by multiplying 2 and adding it to row 3, you obtain the new row 3 values of 0, 3, 4, 12.
