# Area - math problems

Mathematical word problems allow you to practice your mathematics knowledge in everyday life tasks. Word problems train to understand, translate into the mathematical language (e.g., equations), solve it, and check the accuracy and solution discussion.
Choose a topic you want to calculate and improve in.
