It is possible to calculate and transform expressions using the Computer Algebra System originally developed by CASIO. The CAS has many functions; calculating differentials, integrals, limits, sums (), products (), Taylor series expansions, and so forth, expanding and factoring expressions, solving equations and inequalities, and transforming trigonometric expressions. The purpose of the CAS is to obtain solutions instantly, different from those of the ALGEBRA and TUTOR.
	Press a function menu key to display the menu of functions for the type of operation you are trying to perform. "TRNS"....{formula transformation menu} "CALC"....{formula calculation menu} "EQUA"....{equation,inequality menu} For details on commands and their formats, see the [Algebra Command Reference]. To determine the limit of sin (x)/x at point 0. lim(sin x/x, x, 0) To find the Taylor polynomial of degree six for sin (x) at point 0. taylor(sin x,x,6,0)

	In addition to the above, differentiation, integration and calculation of sums and products are available.
	Simultaneous linear equation To solve the simultaneous linear equation x+y=0, x-y=6. solve({x+y=0, x-y},{x,y})	Differential To differentiate x6 with respect to x. diff(x^6)
	Integrate To integrate x2 with respect to x. (x2) Product To calculate the product as the values of x in x2 changes from x=1 through x=5. (X2, X, 1, 5)	Sum To calculate the sum as the values of x in x2 changes from x=1 through x=10. (X2, X, 1, 10)
