This program generates random addition, subtraction, and multiplication problems, asks the user to enter an answer, and tallies correct/incorrect answers. Click "See inside" and look at the comments in the code for suggestions about what you can change. For an added challenge, try adding division problems to the program, but be careful with how you handle decimal places and rounding!
This program is based on this project at Science Buddies: https://www.sciencebuddies.org/science-fair-projects/project-ideas/HumBeh_p022/human-behavior/multitasking-efficiency
