Kiā Orā and Welcome back to my blog post 2021 today in Term 1 Week 10.
We have been learning about reversibility In maths this week.
Okay so this is how reversibility so here is a example
193-66=123 66+4=70
+30 +93
70 100 193
30+93=123
66+4=70
70+30=100
100+93=193
Here is My maths Create I hope you like it.
