Love this.

PS...I don't want to be the "aCkShUaLly" guy but the first problem she solved had an error. She multiplied 4x4 when it should have been 2x4 in the second step.

Only bringing it up in case she wants to edit it and re-upload. Would fit in well with the bloopers reels which are awesome.

We all make mistakes. Its's great she embraces it!

Love her initiative regardless and hope she gets a ton of subscribers!
