• Compare chunk 1 and chunk 2: what is the difference? Notes on Chunk 1: -Grey box for addition and subtraction. Addition label is above the answer. Subtraction is also above its answer. Both are within grey box. Notes on chunk 2: -answers are in white for addition and subtraction just like in chunk 1. But unlike chunk 1 it does not show the inputs for addition and subtraction, only showing the outputs/answers. • Compare chunk 3 with the other chunks. What do you notice? Unlike chunk 1 and chunk 2, chunk 3 only displays the inputs and does not display the outputs. Chunk 1 displays the inputs AND outputs, while chunk two displays JUST the outputs with NO inputs.
