Examples

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

In [2]: x = GF.Random(10); x
Out[2]: GF([ 4, 23,  5,  6, 23, 17, 14, 15,  4, 16], order=31)

In [3]: y = GF.Random(10); y
Out[3]: GF([ 1, 30, 28, 10,  4, 14, 29, 29, 28, 15], order=31)

In [4]: np.subtract(x, y)
Out[4]: GF([ 3, 24,  8, 27, 19,  3, 16, 17,  7,  1], order=31)

In [5]: x - y
Out[5]: GF([ 3, 24,  8, 27, 19,  3, 16, 17,  7,  1], order=31)
