1. (3000 + 240) * 10 =

To solve this expression, we can use the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). According to this rule, we need to perform the addition inside the parentheses first, and then multiply the result by 10.

Adding 3000 and 240 gives us 3240. Multiplying 3240 by 10 gives us the final result of 32,400
