alice-teacher Decrement in a for-loop

[Don Slater]

Carlos,
I am having trouble seeing you image, but I suspect you have a variable that is keeping track of the decreasing value as you count up the appropriate amount… I do not know that there is an easier way to use the count loop for this purpose, and so it is at this point that I will introduce the while loop.

James has an interesting suggestion, well worth considering.

All the best,
Don Slater
