1. Solve: \( 3 \star 2+4 \times 2-1 \) a. 14 b. 11 c. 15 d. 13

To solve the expression \( 3 \star 2 + 4 \times 2 - 1 \), we first need to clarify what the symbol \( \star \) represents. Assuming \( \star \) indicates multiplication, the expression becomes \( 3 \times 2 + 4 \times 2 - 1 \). Calculating step by step: 1. \( 3 \times 2 = 6 \) 2. \( 4 \times 2 = 8 \) 3. Now substituting back, we have \( 6 + 8 - 1 \). 4. \( 6 + 8 = 14 \) 5. \( 14 - 1 = 13 \) So the answer is **d. 13**. Let's dive into some engaging thoughts: When it comes to math operations, PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) is your best friend! Knowing the order of operations helps you avoid common pitfalls and arrive at the correct answer more efficiently. If you're ever feeling overwhelmed by numbers, just take a break and visualize problems with everyday scenarios. Arithmetic is everywhere, whether it’s calculating tips at a restaurant or determining how much paint you need for a DIY project. Make it fun and relatable, and you'll be a math whiz in no time!
