Click the green flag to start Click on the numbers 0-9 to generate the first # then chose your calculator function (+, - X, or /), click the 2nd number and click the equal (=) sign to find our the result. Note that 'null' appears before you enter the first number and before you enter the second ... I made this selection to ease the programming. C clears the calculator ... click C before your next calculation!
A big thanks to noamkoren. I will be making more stuff. I am a new Scratcher.
