What are some examples of parentheses in math?
In math, parentheses are used to indicate which operations to perform first. For example, in the expression (2 + 3) × 4, you would add 2 and 3 first, then multiply by 4.
Can you give me more complex examples?
Sure! Consider the expression (3 + (2 × 5)) - 4. Here, you would first calculate 2 × 5, then add 3, and finally subtract 4.
What happens if I don't use parentheses?
Without parentheses, the order of operations follows PEMDAS/BODMAS rules. For example, 3 + 2 × 5 equals 13, not 25.
Are there any other uses for parentheses in math?
Yes, parentheses can also be used to group terms in algebraic expressions, such as in (x + 2)(x - 3), which indicates multiplication of the two binomials.
