★ For each correctly solved task, points are awarded. If you answer quickly, you will also get a bonus points for speed


What makes customization flexible?
★ you can train one or several operations (addition, subtraction, multiplication, division)
★ negative answers can be disabled for “subtraction” (younger players may not know negative numbers and will not be able to solve task like: 3 - 5 = -2)
★ you can use the standard settings for numbers (one-digit, two-digit, etc.), or you can set your custom range
★ training duration can be limited: 10, 20, 30, ... 120 seconds, or you can play as long as you want
