This section describes sub-expressions.

A portion of an expression can grouped as a sub-expression using round brackets: (...).

When sub-expressions are used, the order of evaluation will be affected as described below:

1. Inner sub-expressions are evaluated before outer sub-expressions.

2. Sub-expressions are evaluated before the base expression.

Examples of sub-expressions:

1. Sub-expressions are evaluated first:

# "1 + 2" is evaluated first, because "(1 + 2)" is a sub-expression
(1 + 2) * 3;

# The above expression is an alias of:
integer.multiply(integer.add(1,2),3);

2. Inner sub-expressions are evaluated first:

# "2 - 4" is evaluated first, 
# because "(2 - 4)" is an inner sub-expression
(1 + (2 - 4)) * 3;

# The above expression is an alias of:
integer.multiply(integer.add(1,integer.subtract(2,4)),3);
