Numbers. Sum cells with conditions

Hello

I have three columns full of numbers; A, B and C.

I need a cell to have a formula that gives me the result of sum the cells of column C when in their corresponding ones in the same row, the value of the cell of A is greater than the value of that of B. That is, if in A5 we have the value 5 and in B5 the value 4, the value of C5 must be sum to that of other values ​​of cells in C where the fact that in the same row the value of A is greater than that of B. I would also need to know the times that happens, that the value of A is greater than that of B in the same row.

Thanks
