In both addition and subtraction, the fnal result should retain as many decimal places as are there in the number with the least decimal places.
E.g., 2.1 + 1.78 + 2.046 = 5.926, is rounded off to 5.9
12.587 - 12.5 = 0.087, is rounded off to 0.1
In multiplication or division, the fnal result should retain as many significant figures as are there in the original number with the least significant figures.
E.g., 3.8 x 0.125 = 0.475, is rounded off to 0.48
4.237/2.51 = 1.68804780876, is rounded off to 1.69
