Let's try some other simple operations before trying the more complicated
expression used earlier for the algebraic operating mode:
123/32

( 27)
Note the position of the y and x in the last two operations. The base in the
exponential operation is y (stack level 2) while the exponent is x (stack
level 1) before the key Q is pressed.
operation, y (stack level 2) is the quantity under the root sign, and x (stack
level 1) is the root.
Try the following exercise involving 3 factors: (5 + 3)
5`3+ Calculates (5 +3) first.
