The number of significant figures is equal

Look at the numbers on which you are operating. Count up the number of sig figs in each. If one of the numbers has fewer sig figs than the other numbers, that number of sig figs will be the same number of sig figs in your answer. You must then perform the operation and round the result to the correct number of sig figs: 29.35 ( 43.678 = 1281.9493 ................
