If the only operation is addition, then 3.
It is: 23+(4*7) = 36.
Assuming that the only permitted operation is addition, then there are 4 combinations.
Impossible, as there are not enough numbers to cover all squares.
ps
Addition of two consecutive positive integers will always make an odd number. Therefore, this is an impossible sum.
