roatee calc

NEWS – If using the calculator that is built into your phone doesn’t have enough features for you, then you’ll want to pay attention to this post. I stumbled upon the Roatee professional scientific calculator and was intrigued by its very unique added feature. The Roatee is designed like a book and opens to reveal the solar-powered scientific calculator on the left side and an erasable LCD writing tablet on the right side. The tablet side totally reminds me of the Boogie Board writing tablets that I have reviewed in the past. This 417 function calc would be great for a student or anyone who wants a really cool calculator. The best news is that it’s only $34.98 from Amazon.

  2. The Tech in that calculator is very very simple/cheap today. Probably $2-$3 TOPS to manufacture. I’m not saying $35 is unreasonable, for those that need it I think it’s a great idea. But imagine taking this back in time to the 1940’s, what leaps in science could this have ushered in the hands of the right scientist or mathematician?

  3. This invention is one of a kind u have it in one not two but one and the pin with a writing board is fantastic idea with the calculator so u can do all types of math along with division,multiplication,subtraction,fraction and more who invented this gets a 5 star review. sincerely sarenity
