jan 1, 20000 BC - the inshago bone,
the inshago bone was
first found in 1950 and was one of the first ways that math was portrayed.
it is one of the oldest
mathematical artefact that we know of. it is currently under the hands
of the museum of science
in Brussels, Belgium. this piece is very improtent to the math
of today because since we found it we have found out how they used
the inshago bone to turn those lines to numbers and how they made
symbols to show the different numbers.
