Answer 2

Hello Students,

◆ Addition/substraction of measured quantities -

• During addition of measured quantities, answer must be expressed with significant figures of least precise measurement.

For example,

• During addition of 2.06 (3 significant figures) and 3.567 (4 significant figures),

2.06 + 3.567 = 5.627

• So our answer must be with 3 significant figures.

2.06 + 3.567 = 5.63

Hope this helped you...
