would you like to brush your teeth with hogs hair? Toothbrushes were invented in china in the late 1400s and were made of hogs hair! the first nylon toothbrush was made in 1983, 23 years before the first electric toothbrush was invented. Then find the year.
<<Then find the year.>>
Which year are you asking for?
The data you are providing is not correct. The first electric toothbrush was not invented 23 years after 1983.
no dawg they just want it put like in a formula or something and then slove it
