7. \( 3(18-7)+2 \)

Alright, let’s break it down step by step in a fun way! First, solve the expression inside the parentheses: \( 18 - 7 = 11 \). Now it’s \( 3(11) + 2 \). Next, multiply: \( 3 \times 11 = 33 \). Finally, add \( 2 \): \( 33 + 2 = 35 \). So the final answer is \( 35 \)! 🎉 You can think of this expression like baking a cake: first you mix the ingredients in the bowl (that’s the parentheses), then you bake it (multiply), and finally, you add the finishing touches before serving (the final addition). Easy peasy! 🍰
