Why do I multiply two voltages?

For each 0, move the decimal point one place to the right. So, .67 x 1 = .67, .67 x 10 = 6.7, .67 x 100 = 67.

There is no general rule covering this situation. In your example, however, (3!)(5!) = 720 = 6!.

Only if you are reversing the simplification process. For example, 3 with a radical of 8. 3 squared is 9, so you multiply 9 under the radical with the eight...

Yes, though it's best to convert to exponential form first. To multiple squareroot2 by cuberoot2, write it as 2^(1/2)*2^(1/3) . Then the rules of exponents make the next step easy...

A number line is not useful in multiplication. Instead, think of multiplying by 20 as first multiplying by 2 (a relatively easy process) and then multiplying by 10 (which is...

This method works with decimals. Multiply and divide by 2 as you would with any other numbers.

I don't see anything wrong with it. Everyone learns differently, so do whatever it takes to help you learn the material. Over time, you'll become more confident with it, and...

To multiply 12x12, imagine that you have two extra fingers on each of your hands, which gives you a run from 6 to 12 from your pinkie to the second...

In another column, create a formula by entering =, then selecting the first value and typing * (which means multiply) before selecting the second value and pressing enter.

Excel will only show the product. If you also want to see the numbers you multiplied, you will have to write them again.
