[1]devide [0,1] into two segments, say the lengths of the segments are
x_1 and x_2, respectively. Let the value
y_1 = x_1 * x_2.
[2]Then divide the segment x_1 into two parts, say with lengths x_{11} and x
_{12}.
And divide the segment x_2 into two parts, say with lengths x_{21} and x_{22
}.
Let the value
y_2 = y_1 + x_{11} * x_{21} + x_{12} * x_{22}
