USING THE ADDITION PRINCIPLE In other words, whatever “we” do to one side must be performed to the other side as well. You may add some number to both sides or you may subtract (since subtraction is really addition of the opposite) to both sides. Problem 2 Solve the following equat...

it was typically done as a rote skill. Students knew that they needed to have two addition equations and two subtraction equations using the same numbers, yet they didn’t have an understanding of what the equations represented. We knew that because we would often see unreasonable results, like...

Eleven students solved the task by using this strategy, which represents almost 10 %. This step caused the biggest problem for the students. The third step (Step 3) is based on Step 1, and just the subtraction was needed. Those students, who correctly made Step 1, made Step 3 correctly...
