Hello fellow mathies! 😁 I have neglected to observe several math days over the last month, and as today is one too I thought it’d be a good time to catch up. I missed 3+13=16 and 3-19=-16 for March, and Mario Day which is March 10th (MAR10). Today, of course, is 4×4=16, or 4²=16.
Have I missed any others recently?
