Welcome to the 65th edition of Math Teachers at Play. First let us have some trivia about 65. First, 65 is the smallest integer that can be expressed as the sum of two distinct positive squares in two ways 65 = 82 + 12 = 72 + 42. Second, 65 is the length of the hypotenuse of 4 different Pythagorean Triangles: 652 = 162 + 632 = 332 + 562 = 392 + 522 = 252 + 602. Third, 65=15+24+33+42+51. Lastly, 65 is the traditional age for retirement in the United States, the United Kingdom, and other countries including my beloved Philippines.
And now, let the math carnival begin!
