We notice the application of the hierarchy-of-operation rules in this selection.
First the y (Step A1). Then, y-3 (Step A2, parentheses). Then, (y-3)x (Step A3,
multiplication). Then (y-3)x+5, (Step A4, addition). Then, ((y-3)x+5)(x
2
+4)
(Step A5, multiplication), and finally, ((y-3)x+5)(x
2
+4)/SIN(4x-2) (Step A6,
division). It is important to point out that the multiplication in Step A5 includes
the first term, ((y-3)x+5) with a second term (x
2
+4), which is already
calculated. To see the steps in calculating these second term, press the down
arrow key

, continuously, until the clear, editing cursor is triggered around
the y, once more. Then, press the right arrow key until these cursor is over the
x in the second term in the numerator. Then, press the upper-arrow key to
select this x. The steps in the evaluation of the expression, starting from this
point, are shown below:
