    In the early 16th century, the Italian mathematician Scipione del Ferro (1465–1526) found a method for solving a class of cubic equations, namely those of the form x 3 + mx = n. In fact, all cubic equations can be reduced to this form if one allows m and n to be negative, but negative numbers were not known to him at that time. Del Ferro kept ...

    That way if a student has answered 7 out of 10 questions correctly, their mark should be: (6*7)/10=4.20, which is graded as Good 4 or average performance. Another common formula is Grade = 2 + ((4* number of correct answers)/total answers). That way if a student has answered 7 out of 10 questions correctly, their mark would be: 2 + (4*7)/10 = 4 ...
