How do I use parentheses to control operator precedence in math?

Can you explain how to use parentheses to control operator precedence in math?

Sure! Parentheses are used to group parts of a mathematical expression, which tells us to perform those operations first.

Can you give me an example?

Of course! In the expression 3 + 5 × 2, without parentheses, multiplication comes first, so it equals 3 + 10 = 13. But if you write it as (3 + 5) × 2, you calculate the parentheses first, resulting in 8 × 2 = 16.

What if I have multiple parentheses?

Great question! You can have nested parentheses. For example, in the expression (2 + (3 × 4)), you first calculate 3 × 4, then add 2, giving you 14.

Are there any rules I should follow when using parentheses?

Yes! Always start from the innermost parentheses and work your way out. Also, be mindful of the order of operations: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
