#math trivia for #March28: #88 is the sum of three squares (not necessarily distinct) What are they?
One way to do it is with 49, 25 and 4.
Another is with 36, 36 and 16.
It turns out that every number can be expressed as the sum of four squares (where 0^2 is a possible choice). (This is Lagrange’s Theorem.) Many, like 88, can be expressed as the sum of just three.
