It means you have to solve the problem in parentheses first.

ex: 2X4+5= 13; 2X (4+5) = 18. The answer is different because

you have to solve the problem in the Order of Operations.

1) Parentheses

2) Exponents like 22

3) Multiplication

4) Division

5) Addition

6) Subtraction

PEMDAS or Please Excuse My Dear Aunt Sally.

What does a number in parentheses mean?

Too many variables to really answer. The context of the number is critical. Is it an Area Code? Is it a negative number on a bank statement? Is it referencing a footnote in a book? Is it following a number such as one (1)? The meaning is entirely dependant on the context. ______________________________________________________________________ Another answer would be that if a number in parentheses is right next to another number, then you are to multiply both numbers if it's a math problem. In some graph tables, f(x) replaces y. Variables, letters that replace numbers, can also be in parentheses.
