Numbers

Type 1; into the Hope interpreter like this:

>: 1;

The Hope system responds with

>> 1 : num

This tells us the result of evaluating the expression 1 is 1 and the type of the expression is num. i.e. a number (usually called an integer).

Now try the following

>: 1+1;
>: 1+2*10;
>: (1+2)*10;

The replies given by Hope are:

>> 2 : num
>> 21 : num
>> 30 : num

So every expression is evaluated and the type of each expression is given.
