For example, having selected the Step/step option, the following screens show

the step-by-step division of two polynomials, namely, (X

+3X-2)/(X-2). This

is accomplished by using function DIV2 as shown below. Press ` to show

the first step:

The screen inform us that the calculator is operating a division of polynomials

A/B, so that A = BQ + R, where Q = quotient, and R = remainder. For the

case under consideration, A = X

+3X-2, and B = X-2. These polynomials

are represented in the screen by lists of their coefficients. For example, the

expression A: {1,-5,3,-2} represents the polynomial A = X

+3X-2, B:{1,-2}

represents the polynomial B = X-2, Q: {1} represents the polynomial Q = X, and

R:{-3,3,-2} represents the polynomial R = -3X

At this point, press, for example, the ` key. Continue pressing ` the key to

produce additional steps:

Thus, the intermediate steps shown represent the coefficients of the quotient and

residual of the step-by-step synthetic division as would have been performed by
