Getting started 43

A message appears asking if you want to create a

variable called ME. Tap or press

E to

confirm your intention. You can now use that variable in

subsequent calculations: ME*3 will yield 29.6088132033,

for example.

You can also create variables in CAS view in the same

way. However, the built-in CAS variables must be entered

in lowercase. However, the variables you create yourself

can be uppercase or lowercase.

See chapter 22, “Variables”, starting on page 427 for

more information.

As well as built-in Home and CAS variables, and the

variables you create yourself, each app has variables that

you can access and use in calculations. See “App

functions and variables” on page 109 for more

information.

Complex numbers

You can perform arithmetic operations using complex

numbers. Complex numbers can be entered in the

following forms, where x is the real part, y is the

imaginary part, and i is the imaginary constant, :

• (x, y)

• x + yi (except in RPN mode)

• x – yi (except in RPN mode)

• x + iy (except in RPN mode), or

• x – iy (except in RPN mode)

To enter i:

• press

ASg

• press

Sy.

There are 10 built-in variables available for storing

complex numbers. These are labeled Z0 to Z9. You can
