Examples

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

In [2]: x = GF.Random(10); x
Out[2]: GF([ 3, 30,  8, 11, 25, 17,  2, 16,  5, 25], order=31)

In [3]: y = GF.Random(10); y
Out[3]: GF([ 3, 28, 20,  4,  9, 27, 17, 16, 30, 30], order=31)

In [4]: np.subtract(x, y)
Out[4]: GF([ 0,  2, 19,  7, 16, 21, 16,  0,  6, 26], order=31)

In [5]: x - y
Out[5]: GF([ 0,  2, 19,  7, 16, 21, 16,  0,  6, 26], order=31)
