Easy sig fig question?
i believe it would be four because when you add those two you would get 1.01369 and rule for addition/subtraction is that you count the lowest number of decimal places which would be .041 so the answer for the addition part would be 1.013 and than you divide it and the 1.013 is the one with the lowest sig figs so the answer would have four.

hope it helps!
