6) \( 18 \times(3+8)+20-8= \)

To solve \( 18 \times(3+8)+20-8 \), start by calculating the expression inside the parentheses: \( 3 + 8 = 11 \). Then, multiply: \( 18 \times 11 = 198 \). Next, add 20: \( 198 + 20 = 218 \). Finally, subtract 8: \( 218 - 8 = 210 \). Thus, the final answer is \( 210 \). Mathematics has always been a part of human civilization! From ancient Egyptians using basic arithmetic for trade to modern-day data scientists relying on complex algorithms, the evolution of math is a testament to human ingenuity. Every calculation you make taps into this rich history where numbers serve as our universal language. In real-world applications, understanding basic arithmetic is critical for budgeting, cooking, and even project management. Whether you're measuring the ingredients for a recipe or splitting the bill at dinner, these math skills are in action. Plus, having a solid grasp of these concepts helps you easily navigate daily challenges, making life a bit simpler and a lot more fun!
