Today’s Puzzle:
Earlier this week the United States surpassed 400,000 deaths from the novel coronavirus. Over 2,000,000 people have died from the virus worldwide. Most of these people died in isolation away from loved ones. Most of the millions of tears shed have also been in isolation. New and more contagious strains of the virus have arisen in various parts of the world threatening to make the death toll worse and the number of tears to grow exponentially. Each of us can and must do our part to flatten the curve and thus restrict the number of deaths and the number of tears.

thank you for these words. Any single thing we do seems like a single drop in the ocean, but the ocean is made of nothing more than a collection of single drops. Each of us doing what we can do, while keeping those who have gone in our hearts, is all we can do and that’s all we need to do.
Thank you for your words as well. It is easy to forget that a mighty ocean is made from millions of single drops of water. We can only do what we can do and not more than that.
Very good points, we do add up, together.
Thank you for your focus on mathematics, and I do hope that you’ll have time to drop by and let me know how you think our math and Adult Education posts might complement one another, in adding some good to the ocean?
Best regards,
