making it square

58 is an interesting sad number. 

Cause when you square it, you get 3364, a happy number! (3364 --> 70 --> 49 --> 97 --> 130 --> 10 --> 1) And 58 is the only one. So I guess you can say 58 is the least saddest of the sad numbers :/

4^2=16 (still sad)

16^2=256 (normal)

37^2=1369 (normal)

89^2=7921 (normal)

145^2=21025 (normal)

42^2=1764 (normal)

20^2=400 (normal)

so all y'all got to do to 58 to make it happy is to make it square
