## Getting Started

Maxima is a command-line system. You enter a command, obtain an answer
and can enter the next command.

A command is an expression that can be spread over many lines and is closed
with a semicolon. e.g.

(%i1) 14*(7 + 3);

You obtain this answer:

(%o1) 140

Note that nothing will happen when you forget to enter the semicolon.
Maxiama will simply wait for further input

You can enter an expression that contains variables:

(%i2) (x + 2)*(x - 3);

Maxima answers this expression in unsimplified form:

(%o2) (x - 3) (x + 2)

Note that you have to type an asterix to denote multiplication.
Maxima prefers a writing form that does not use a multiplication
operator: Like in traditional mathematical notation, multiplication
is implicit.

Perhaps you would prefer to see the product expanded. This is
something that you have to ask for.

expand(%);

2
(%o5) x - x - 6

Note the interpretation of powers:

x^3^4;

81
(%o2) x

(x^3)^4;

12
(%o4) x

We see that x^3^4 is evaluated as x^(3^4), not as (x^3)^4.
