Hi,
I'm Francesca from St Francis of Assisi School. Today in Week 7 Term 2 we have been learning about Reversibility To solve subtraction problems with my maths teacher for this week. How you do Reversibility. How you do Reversibility is if there is a question like 34-18=16 what you do is you + 2 on the 18 which then makes the Question 20+14=34= so the answer is 34 then you + 2 on the 14 which is 16 so the full answer is 16. I hope I have made it easier to understand for you I have made a Google Drawing with some more Reversibility Questions for you to look at and yeah If you have any questions comment down below.
