• Adding scalar quantities:

  • Scalars are quantities that have only magnitude.

  • To add scalars, simply add their magnitudes.

  • The result is a scalar with a magnitude equal to the sum of the magnitudes.

• Subtracting scalar quantities:

  • Subtracting scalars is similar to adding them.

  • To subtract scalars, subtract their magnitudes.

  • The result is a scalar with a magnitude equal to the difference of the magnitudes.

WHENEVER SCALAR QUANTITIES ARE ADDED OR SUBTRACTED THE UNIT REMAINS THE SAME.
