Place Value Flowchart

Today for maths my group tapo are focusing on using a Place Value House to solve equations. For this task We had to answer three questions which included: What is a place value, How does it work, and How you use it to solve problems. We also had to explain how to solve equations by using the Place Value House. I learnt that when you add and multiply it goes bigger and it moves to the left of the Place Value House and if it is subtracted it moves to the Right of the Place Value House.and if the 1 has a 9 and you + 1 it transfers from the 1 to the 10 and then the 1 become 0
