Example 5:

Your fx calculator is capable of performing multi-stage

calculations as this example will demonstrate.

Perform the calculations,

(16.26 + 18.42 ) + (−4.58 + 11.83 )

(16.26 + 18.42 ) − (−4.58 + 11.83 )
(16.26 + 18.42 )(−4.58 + 11.83 )

(16.26 + 18.42 )

(−4.58 + 11.83 )

Let A be the first complex number and B the second
complex number, for all four calculations, use the

following keystrokes,

CQ(A)+Q(B)Q(:)
