What is the Three-Member Equation Generator?
This generator creates simple examples with three single-digit numbers and the operations of addition and subtraction. The exercise is designed so that the result is never negative, which is suitable for first graders.
Usage
An example with three numbers will be displayed on the screen. Your task is to calculate the result and write it in the empty box. You can check the correctness of your answer by pressing the "CHECK" button. For a new example, press the "NEW EXERCISE" button.
