How Did my Teacher Do this

[gabe]

First, create the tile:

<convertibleCorvette.speed> set value to <1>

Then, drag another convertibleCorvette.speed variable onto the <1> placeholder.

Click the down arrow next to the variable you just dragged over and select math from the drop down list, "+", and then "other...".

Type in the value you want.

So much for teaching.

Did the teacher ask that you complete the assignment?
