We’re excited to announce a brand-new exercise on BrainScale:
Tips & Tax – Train your real-life mental math skills
This exercise helps you practice calculating:
Sales tax (based on U.S. state tax rates)- Tip amount (selectable percentage)
- Final total — fast and accurately, just like you’d do at a restaurant
Whether you’re dining out or just want to sharpen your mental math for everyday use, this challenge gives you practical brain training in under a minute.
Part of Our New Initiative: Smart Life
Smart Life is a new section of BrainScale dedicated to real-world thinking skills. We’re starting with practical math (like Tips & Tax), and we’ll be adding more exercises soon—like bill splitting, shopping math, and more.
