ا پیش از اختراع عددهای دهدهی ، هر واحد را به شصت قسمت برابر تقسیم می کردند و در صورت لزوم ، هر یک از آنها را نیز به شصت قسمت کوچکتر تقسیم می کردند و همین طور ادامه می دادند مانند تقسیم هر ساعت به شصت دقیقه و هر دقیقه به شصت ثانیه .

انجام این محاسبات با این عددها کار بسیار مشکلی بود ، اما حدود 600 سال پیش یک دانشمند این مشکل را برای همیشه حل کرد ، او هر قسمت را به جای تقسیم به شصت به ده قسمت تقسیم کرد.

این ریاضیدان برای اولین بار از عدد دهدهی اختراعی خود ، برای نوشتن عدد پی استفاده کرد. او عدد پی را به کمک  850360368ضلعی منتظم تا هفده رقم اعشار محاسبه کرد. تا دویست سال پیش ، اعداد اعشاری را به صورت های مختلفی می نوشتند برای مثال به صورتهای 75/4 یا (75) 4 یا 75| 4.

آیا مخترع عددهای دهدهی را می شناسید ؟ بله ، او کسی نبود جز ریاضیدان و ستاره شناس برجسته ایرانی «غیاث الدین جمشید کاشانی» او در بین دانشمندان به «کاشی» معروف بوده است

First off I would like to say terrific blog! I had a quick question that I'd like to ask if you don't mind.
I was curious to find out how you center yourself and clear your thoughts prior to writing.
I've had trouble clearing my thoughts in getting my
ideas out. I truly do take pleasure in writing however it just seems like the
first 10 to 15 minutes are generally lost just trying to figure out how to begin. Any
ideas or tips? Kudos!

Hi, There's no doubt that your blog might be having web browser compatibility issues.
Whenever I look at your blog in Safari, it looks fine however, when opening in Internet Explorer, it has some overlapping issues.
I merely wanted to give you a quick heads up! Apart from that, excellent website!

Wonderful blog! I found it while surfing around on Yahoo News.
Do you have any suggestions on how to get listed in Yahoo News?
I've been trying for a while but I never seem to get there!

The other day, while I was at work, my cousin stole my apple
ipad and tested to see if it can survive a 25 foot drop, just
so she can be a youtube sensation. My iPad is now destroyed and she has 83 views.
I know this is totally off topic but I had to share it with someone!
