What are some examples of parentheses in equations?

Can you give me some examples of how parentheses are used in equations?

Sure! Parentheses are used to indicate which operations should be performed first. For example, in the equation 3 + (2 × 5), you would calculate 2 × 5 first, giving you 3 + 10, which equals 13.

What about a more complex example?

Absolutely! Consider the equation (4 + 3) × (2 - 1). Here, you first solve the expressions in the parentheses: 4 + 3 = 7 and 2 - 1 = 1. Then, you multiply the results: 7 × 1 = 7.

Are there any rules for using parentheses?

Yes! The main rule is to always perform operations inside parentheses first. This helps clarify the order of operations in complex equations.

Can you show me an example with multiple parentheses?

Sure! In the equation (2 + (3 × 4)) - (5 - 2), you first calculate the inner parentheses: 3 × 4 = 12, then 5 - 2 = 3. So it becomes (2 + 12) - 3, which simplifies to 14 - 3 = 11.
