Are you referring to brackets? Use of ( ) is important in secondary level.

Using brackets also important to ensure the + and - sign of the product.

You take away ( ) straightaway so the -7 have to extra careful.
- x - = + ( - time - get + result )
+ x + = + ( + time + get + result )
- x + = - ( - time + get - result)
+ x - = - ( + x - get - result)
- x - = + ( - time - get + result )
+ x + = + ( + time + get + result )
- x + = - ( - time + get - result)
+ x - = - ( + x - get - result)
