LEARN
Column multiplication, like in a notebook, step by step.
Select the top two-digit or three-digit number, then the bottom one-digit, two-digit or three-digit. The numbers will be randomly selected.

Substitute, consistently, the correct answers as you did in the notebook.
Do not forget to keep tens in mind to add to the next number.
If the answer is correct, it will be bright. The wrong answer is dull. Erase the wrong answer by pressing "C", enter the correct answer.
Continue this way until you have entered all the correct answers.
Once you have entered everything correctly, the "V" with animation will prompt you to move on to the next example.


TEST
If you need to prepare for a math test or test paper, be sure to take the test! The test is like a control at school. There you are given examples in random order without prompts and without a calculator. If even one answer is wrong, the whole example is wrong.

Click on the timer and the countdown will begin. Choose multi-digit numbers.
Solve examples. There will be 10. Substitute the answers sequentially.
After you put the last number, you will see your correct and incorrect answers.

To go to the next example - press "V". Resolve will not work - it's a test. After you solve all the examples, the test will end and the number of correct answers will be automatically saved.


STATISTICS
After passing the test, the result will be saved to statistics.


CALCULATOR
The column calculator will show you not only the correct answers, but also their solution.
Will help you do your homework or check yourself.
You can use it when teaching. If you are doing a test, you cannot use the calculator - it is still a test - so without prompts - use your head.


LUCK!
