operation, which can then be used as a unit.For example, we consider defining the square "a number squared that is itself multiplied by itself", namely:（define (square x) (* x x)）OK, now we have a compound process whose name is square (definition).Once we've defined square, we can use it as a unit:(square 10)100(square (+ 2 5))49We can do it. Square as a basic component to construct other operations, such as X^2+Y^2, can be described as:(+ (square x) (square y))We define this operation as Sum_o
