# You can also use !a( i ) in place of
K3(CPLX)1(
i ).
k Arithmetic Operations [OPTN]-[CPLX]-[ i ]
Arithmetic operations are the same as those you use for manual calculations. You can even
use parentheses and memory.
Example 1 (1 + 2
i ) + (2 + 3 i )
AK3(CPLX)
(b+c1(
i ))
+(c+d1(
i ))w
Example 2 (2 +
i ) × (2 – i )
AK3(CPLX)
(c+1(
i ))
*(c-1(
i ))w
k Reciprocals, Square Roots, and Squares
Example (3 + i )
AK3(CPLX)
!x(')(d+1(
i ))w
