9) \( 20 \div(4-(10-8)) \)

Let's break down the expression step by step! First, we evaluate the parentheses: \( 10 - 8 = 2 \), so it becomes \( 4 - 2 \). Now we have \( 20 \div (4 - 2) \), which simplifies to \( 20 \div 2\). Finally, dividing gives us \( 20 ÷ 2 = 10 \). So, the answer is \( 10 \). Math magic in action! 🌟 Math puzzles like these can be super fun and strengthen your calculating skills! Try creating variations by changing the numbers or operations and see how it affects the outcome. Engaging with numbers in playful ways can help make math feel less daunting and more like a game you can master. 🧩✨
