The font is the same and very readable and it has almost every function of the TI-84 including sin, cos, tan, e^x, ln, etc. This $14 calculator even has some features the TI84 lacks--MultiView the most useful. On the TI-84, an expression might appear as (2-3x^2)/(4-1/(2x)), but this bargain calculator formats it like you´d write in on paper, exponents, fractions and all.
The calculator has probability functions, including nCr, factorial!, and log/ln. It can do roots bigger than 2 without having to write ^(1/3) for the third root for example--it writes a small three, and puts the number/expression UNDER THE ROOT LINE, which is extremely helpful. You can also input an expression like y=sqrt(x+2) and the calculator outputs a table with coordinates, starting with x=1,2,3, etc. You can change the ´steps´ between x-values, as well as just put in any x-value and see the corresponding y-value. This feature is very powerful and quite useful.
Just a word of caution: the T1-34 (a similar product) is more expensive, uglier, and has a horrendous button layout--for example, to compute the sine, cosine or tangent you must go into the trig menu, scroll to the function you want (inverse tangent is sixth on the list) then press enter, then type in the angle. On the TI-30XS you press sin/cos/tan, or for the inverse trig functions, 2nd and sin/cos/tan, just like on the TI-84. The natural log is also hidden like that.
In summary this TI-30XS has almost every feature of the TI-84 (except graphing) and is an incredible bargain.. And summed up by saying Perfect Scientific Calculator with graphing-calc features. Currently TI-30XS Multiview Calculator has an overall rating of 8 over 10.
