For iPad or iPhone or iPod in school hours: Skype
For other times: Skype or a gadget to add, subtract or do any maths thing without you having to think.
I prefer the former.
SKYPE CONVERSATION Girl 1: Stop Skyping me! I am doing maths!
Girl 2: On your 'calculator' on your iPad, huh?
Girl 1: Yeah. I am. haha ;)
Girl 2: You are skyping your maths
1. Somethin that makes man dumb
2. Something that has made cheating easier for man (in maths)
3. Somethin you shove batteries in and it does your math homework
