What customers say about "Size & Weight"
Texas Instruments TI-84 Plus Graphics Calculator, Black
  • Very light weight but not to the point that it feels fragile.
  • Amazing size, comfortable in the hand and nice to use.
  • It is easy to carry with you because it does not weigh too much.
  • Finally the colour scheme and font type and size is difficult to read: Colours need to reflect light, not absorb it and font sizes should be larger.
  • Its size does not allow it to be a highly portable pocket unit but it is not designed for that anyways.

What customers say about "Display"
Texas Instruments TI-84 Plus Graphics Calculator, Black
  • It has a nice size display and big tactile buttons. Make sure to read the instructions and play with it otherwise you won't be able to perform certain operations.
  • The display is clearer to follow due to the usage of modified symbols and text sizes, and the scrollback feature to grab prior results or formulas is a must-have.
  • The calculator is very good for scientific work. I like the large display.
  • Calculator with small, low resolution black and white screen and a fraction of processing power of today's phones, music players, tablets etc.
  • My only complaint is how hard it is to read the screen in low lighting, but that's expected with the kind of display this product uses.

What customers say about "Features"
Texas Instruments TI-84 Plus Graphics Calculator, Black
  • This calculator has made my work so much easier. It is a little big in size but does an awesome job and more. Highly recommend it.
  • Its memory is also useful for making very precise calculations.
  • I think its memory functions are what make it so useful. I may have a few equations that I use all the time during a semester.
  • We have not downloaded any apps yet but they look very useful. The amount of ram and archive memory is nice too.
  • There is a tiny battery in the calculator. I thought it was a back-up battery in case the main batteries went out but looked a little too small for any kind of real work.
