   Trying to invent a pen which can write on leather, a tanner John J. Loud
invented the first ballpoint pen and patented it in 1888 in America. This pen had a
small steel ball which was placed so it could not fall out nor fall in but it still
could rotate freely. This invention was not commercially viable and could not be
used for writing. Because of that patent lapsed in time.

xanh:/........./..13../

đỏ:/............/...13.../...15.../

tổng là 167

tổng số bút đỏ và bút xanh hơn bút tím số chiếc bút là:
