Hello @leosmart. First, welcome to Hive. A nice introduction. I see you have a love of mathematics and love to teach. A dedicated profession. Happy you chose to join. The key, I feel to a successful journey here is to publish quality content. Then find communities or groups that interest you and engage with others.
Did you know that Peakd allows you to use 10 tags? Make use of the tags for your posts for such content as food, etc.
I wish you a good journey on Hive. Look forward to engaging with you again soon.
