We now study the operations of multiplication and division on fractions as well as on decimals

In calculations involving more than one arithmetic operation, rounding off to the proper number of significant figures may be done once at the end if all the operations are multiplication and/ or division or if they are all additions and/or subtractions but not if they are combinations of additions or subtractions with multiplications or divisions.
