Question about Casio FX-300W Plus Calculator
All of a sudden, the screen of my calculator is showing up incomplete numbers i.e the 0 and all other numbers are showing up partially, i.e 3 and 7 both show up as 1 and the calculations are not working either.
Haven't heard of it giving nearest whole numbers before. But have you tried pressing SHIFT and then SETUP (upper right hand corner next to ON button) and then pressing 2 (LineIO)? Or perhaps you're in different MODE?

I took statistics last semester and I don't really remember how, but after you enter your data, you press SHIFT, then STAT (on the 1 key), then I think it's under 5 (VAR), and maybe Xon-1? Eh, funny how long you remember this stuff for....

Yeah I had the same problem, you need to open your calculator and check if all the screen cables is alright, i had just put sellotape on the back of the screen from inside so that the screen hold better, and it works for me if for you not maybe something broken in the schema but try it. The thing I know for sure the problem is in the screen or from where it get the data the schema. Tell me if it's working

If it is too dark
Try reducing the contast as follows
1.Press [2nd] key and release it
2.Press [DownArrow] and release it
3. Keep repeating the sequence until contrast is adequate.
If it is too light increase contrast
To increase contrast Do the same but press [UpArrow] instead of [DownArrow]
Hope it helps

your calculator will never allow you to enter a negative exponent. so heres what you do.Any negative exponent of a number can be reversed and turned into a fraction for example 4^-1=1/4 or 8^-2=2/8=0.25. Hope this helps.
