@mimib1230 i bought one when i was 14 and gave up, im maybe gonna start again because i see 12 year olds adding 5 digit numbers together in their brain in like 5 seconds... amazing.

Why do calculations in your head? Because it teaches you number sense. How many times have I been given the wrong change in stores because the cashiers do what the register tells them, like stupid little robots. They aren't 'filling their heads', they are developing their heads.
But, I still hate their little song.

لانه يعتمد علي الذاكره البصريه في حفظ شكل العداد زي الكاشير و كاتب الاله الكاتبه اللي بيكتب بسرعه دون ان ينظر الي الاله الكاتبه هل هو عبقري رغم انه يستخدم كلتا يديه اثناء الكتابه و يتذكر شكل لوحه المفاتيح التي يكتب عليها ابو دبلوم تجاره !!!

What these schools are doing is castrating children for life a head.

@Lamboragon Yeah, totally agree with you! Why use your head when a calculator can do the trick? and tablet pcs and ipad or even smart phones which are easily available can all do this!

as a major in neurology 4:34 makes me mad since that is a load of bull

You were still learning how to read in HIGH SCHOOL? lol its definitely not the USA's fault you process slow. I dont know anyone like that.
But anyways USA schools are behind
This has the uncanny ability to make me feel stupid, even though my major is math.

Very interesting. I am going to buy an abacus now. I am fifteen, I wonder how effective it will be if I train. Hm. We will see.
