The expression V − E + F is an illustration of the Euler's formula.
The expression V − E + F is always 2
The equation is given as:
V - E + F = 2
Where:
According to the Euler's formula, the relationship between V, E and F is:
V + F = 2 + E
Subtract E from both sides
V - E + F = 2
Hence, the expression V − E + F is always 2
