Hmmm. While searching for some unrelated program, I uncovered a program that I wrote which found the following identities:
13 + 123 = 93 + 103
23 + 893 = 413 + 863
83 + 533 = 293 + 503
93 + 343 = 163 + 333
93 + 583 = 223 + 573
103 + 273 = 193 + 243
173 + 763 = 383 + 733
303 + 673 = 513 + 583
513 + 823 = 643 + 753
Why is this interesting? It’s really not. I just kind of like math.
