Hi steemians :D Hope you're all doing great.
A while ago, my cousin @kyrie1234 encouraged me to post about my learnings in mathematics. So starting this day, I'll be posting some of my learning in mathematics here. I hope that you'll learn something about my posts soon. I hope you guys will support me.
Thank you and have a happy holidays :D
