Training mastery level
Examples with three numbers
Practice your mental arithmetic skills with three numbers using our trainer. The examples consist of two arithmetic operations, where you can get the correct answer only by solving them correctly and sequentially.
Adjust the difficulty level and add negative numbers and any basic operations to the tasks: addition, subtraction, multiplication, and division.
You may also find the bracket expansion trainer useful.

Timed training sessions
The green bar at the bottom shows the remaining training time.
You can noticeably improve your skills by doing 3 training sessions of 5 minutes each day. At the end of each session you will see detailed statistics for your answers. The longer the session, the bigger the bonus to your experience points.
Answer time limit
The blue bar at the top shows the remaining time to answer.
The time limit encourages you to memorize rather than calculate basic examples (multiplication tables, addition, and so on).
For more complex examples, the limit motivates you to calculate faster, but if you do not have time to solve a problem, you can always increase the time for one question or disable this feature entirely.
