Examples

In [1]: GF = galois.GF(31)

In [2]: x = GF.Random(10); x
Out[2]: GF([29, 11,  8,  2, 11,  1, 12,  0, 22, 20], order=31)

In [3]: y = GF.Random(10); y
Out[3]: GF([ 7, 21,  2, 19, 24, 16, 18,  9, 19,  4], order=31)

In [4]: np.subtract(x, y)
Out[4]: GF([22, 21,  6, 14, 18, 16, 25, 22,  3, 16], order=31)

In [5]: x - y
Out[5]: GF([22, 21,  6, 14, 18, 16, 25, 22,  3, 16], order=31)
