Television

When we add to the difference between the numbers 1704 and 654 the difference numbers 14920 and 14042, we get a year in which television was invented. How many years people known the TV?

Correct result:

x =  92

Solution:

x=2020((1704654)+(1492014042))=92x=2020-((1704-654)+(14920-14042))=92
