Physics

# The accuracy of measurement also lies in the way the result is expressed. The number of digits to which a value is to be expressed is one digit more than number of sure numbers. Rules do exist to deal with number of digits after an operation is carried out on the given values. The error can be minimised by many trials and using the correct methods and instruments.The number of significant figures can reduces in

Subtraction

##### SOLUTION
In subtraction of two significant figures of same value the no. of significant figures may reduce.
