The rule for parentheses is that what is inside parentheses is
calculated first.
In (12 - 6 + 2)
everything is inside parentheses,
so the parentheses don't have any effect.
But they don't hurt anything.
When there are sets of parentheses inside parentheses the innermost set of parentheses is calculated first. The innermost set of parentheses are nested within the outer set. For example:
( 5 * (1 + 2) ) / 3 = ( 5 * 3 ) / 3 = 15 / 3 = 5 ------- --------- innermost do next so do first
What will the following program print to the screen:
PRINT (4 * (10 - 7)) / 6
