The document describes an interactive simulation that measures the time it takes to complete three writing projects by writing letters, Roman numerals, and numbers in different colors. It runs the projects row by row, writing each item in a row before moving to the next. As it runs, it displays the items written and the elapsed time. The total time taken to complete all projects row by row is just over 1 minute and 7 seconds.

1. Numbers simulation
A interactive demonstration
Marcus Hammarberg

2. Simulation goals
• Three projects
– Write letters: A – J, with blue pen
– Write roman numbers: I – X, with red pen
– Write numbers: 1 – 10, with black pen
• Measure two times:
– Time to complete each project
– Time to complete all project
• Run two times:
1. Row by row
2. Column by column

3. ROW BY ROW RUN
DOING ALL PROJECT AT ONCE
