What is the formula to add two of the lowests numbers in a group of cells
=sum(small(b1:b4,1)+(small(b1:b4,2)))
The SUM in your solution is obsolete since it sums a single value, which already is the sum of two other values (+ already means: sum the values left and right to the operator)
=SUM(SMALL(B1:B4,1),SMALL(B1:B4,2)) – or –
=SMALL(B1:B4,1) + SMALL(B1:B4,2)
Hi
If the number of cells to be added increases it may become interesting to use:
=SUMPRODUCT(SMALL($A$1:$A$10;ROW(A1:A2)))
