Consider a circuit which has a 3-V (ideal) battery connected in series with a 100-$\Omega$ and a 200-$\Omega$ resistor (series resistors). The voltage across the 100-$\Omega$ resistor will be 1 V, and across the 200-$\Omega$, 2 V.

287,229 | I dual booted ubuntu 12.04 LTS with Windows 8, but I wanted to get rid of ubuntu. So I got EasyBCD (on windows 8) and removed Ubuntu following a tutorial on youtube, then I got rid of the Ubuntu partitions. After restarting my Sony Vaio, it went to grub rescue and I'm not sure what to do. Help please! Much appreciated!... | 2013/04/28 | [

] | Here is what you need to do:
1. Burn an Ubuntu ISO image onto a USB drive or a DVD to make a live USB/DVD.
2. Boot into live mode ("Try Ubuntu" option).
3. After it boots up, press `Ctrl`+`Alt`+`T` to bring up the Terminal.

] | The second `->` isn't needed, actually.
Here's the deal: All Perl array values and hash values must be scalars. That means either a string, number, or array/hash reference (and not a plain old array or hash).
So the first `->` operator dereferences the array and gets at the x'th row. In there is-- not an array, but a... | When you
```
push @array, [@row];
```
you are pushing a *reference* to an array. This is necessary because of Perl's rule that arrays are flattened. So $array->[x] is a reference to the row array, not the row array itself. However, between subscripts, the arrow is optional. So `$array->[x]->[y]` is exactly the same ... |
