Equation (1) and (2) are arithmetic expressions of numbers.

uation (1) is sum of Xn numbers.

Equation (2) is sum of Xij numbers, where i =1....i and j=1.....j

Is it possible to represent equation (3 ) in a condensed form.as i have represented sum of numbers by sigma.

Note:

Xij: Can take any values and are independent of others, there is no relationship between the values (so representation by factorial has to be discarded...)

atlast: Xij is decimal.:

For example if i have 4 values in equation (3): which are x11=.9,x12=.9,,x21=.8,x22=.98

the output
