Using Array And Scalars

import numpy as np

# creating an array
arr1 = np.array([(1, 2, 3, 4), (8, 9, 10, 11)])
arr1

array([[ 1,  2,  3,  4],
       [ 8,  9, 10, 11]])

# multiplication
arr1 * arr1

array([[  1,   4,   9,  16],
       [ 64,  81, 100, 121]])

# substraction
arr1 - arr1

array([[0, 0, 0, 0],
       [0, 0, 0, 0]])

# division
1 / arr1

array([[1.        , 0.5       , 0.33333333, 0.25      ],
       [0.125     , 0.11111111, 0.1       , 0.09090909]])

# power
arr1 ** 3

array([[   1,    8,   27,   64],
       [ 512,  729, 1000, 1331]])
