Subtraction Using Sub Table

An incomplete number statement (for instance, 9 - 1 = ) appears at top of the screen. The program tells the student to click on the first number (9) which is highlighted in red in the left column, and then to click on the second number (1) which is highlighted in green in the top row. The answer (8) now gets a blue highlight, and the program tells the student to click on the answer. The answer moves into the missing space in the number statement, and the program voice says “nine minus one is eight.”
