How can you correct mistakes in a letter typed on a traditional typewriter?

Answer 1

Correction fluid or correction tape is used to cover (or in some cases remove) the incorrect typing. It is vastly easier to do while the typed page is still in the typewriter.

Answer 2

To correct mistakes on a letter typed on a traditional typewriter, you can use correction fluid to cover the error and then retype the correct character over it. If the mistake is minor, you can also use a typewriter eraser to erase the character before retyping it. Be sure to let the correction fluid dry completely before continuing typing on the paper.
