The 18th-century Swiss mathematician

**Leonhard Euler**(1707–1783) is among the**most**prolific and successful mathematicians in the history of the field. His seminal work had a profound impact in numerous areas of mathematics and he is widely credited for introducing and popularizing modern notation and terminology.Keeping this in view, what is Euler's first name?

Leonhard

**Euler**was an 18th century physicist and scholar who was responsible for developing many concepts that are an integral part of modern mathematics.Who discovered e?

It was that great mathematician

**Leonhard Euler**who discovered the number e and calculated its value to 23 decimal places.What is a Euler's rule?

**Euler's Formula**.

**Euler's formula**can be understood by someone in Year 7, but is also interesting enough to be studied in universities as part of the mathematical area called topology.

**Euler's formula**deals with shapes called Polyhedra. A Polyhedron is a closed solid shape which has flat faces and straight edges.
