What is subtraction?

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

The mass of a box measured by a grocer's balance is 3.1 kg. Therefore, the mass of the box in grams is 3100 grams. Now, Two gold pieces of masses 22.35g and 22.39g are added to the box.

A) The total mass of the box is,

Total mass = 3100 g + 22.35g + 22.39g

                   = 3144.74 grams

                   = 3.14474 kg ≈ 3.145 kg

B.) The difference in the masses of the pieces is,

Difference = 22.39 g - 22.35 g

                  = 0.04 g

Hence, The difference in the masses of the pieces is 0.04 grams.
