Why is the apple’s position 90 in the Unit 3 assessment? How can I explain this to my students. Consider the following program (blocks and text) ![](https://assets.learnosity.com/organisations/154/6fdb0aa7-cb14-4a2e-b409-227dc23f2b42.PNG) What is the apple’s x position at the end of this program? ---

Hi dlgleason, Even though the apple’s 🍎 position is initially 20, it is then updated by the value of the banana 🍌 , which is 60 and then added 30, giving you the resulting value of 90. ---

If they thought it was 100, the explanation would be that the computer does the computation line by line. When it gets to line 3 it replaces apple.x with the current value of banana.x, which is 60, +30. It does not look ahead to the final value of banana.x in line 4.
