Answer 2

It seems you're giving a math expression and claiming it to be worth 30 points. Let's evaluate the expression to check if it indeed equals 30:

2 + 3 × 2 - 1

To evaluate the expression, we follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

In our expression, there are no parentheses or exponents, so we move to the next step:

2 + 3 × 2 - 1 = 2 + 6 - 1 (Perform the multiplication: 3 × 2 = 6) = 8 - 1 (Perform the addition: 2 + 6 = 8) = 7 (Perform the subtraction: 8 - 1 = 7)

The result of the expression is 7, not 30. So, I'm afraid you didn't get 30 points for that expression. If you have any other questions or need further assistance, feel free to ask!
