Dutch mark average calculator
During the calculation:
Use 'x' for the weight, per example [5x2] for a 5.0 that counts 2 times.
A [;] means that you're adding another mark. Per example [5x2; 6 = 5.3].
It won't calculate marks under or above the range 1.0 - 10.0.
The calculator will accept comma numbers and dot numbers.
