numpy adding columns

[rwahdan]

I just a solution but if anyone can think of a better way please share...

import numpy as np
numbers = np.array([
    [2,4],
    [8,10],
    [50,100]
    ])
  
add = numbers[:,0] + numbers[:,1]
add = add.reshape(3,1)
mul = numbers[:,0] * numbers[:,1]
mul = mul.reshape(3,1)
numbers_add = np.hstack((numbers, add))
numbers_mul = np.hstack((numbers_add, mul))
print(numbers_mul)

the results:

Output:
[[   2    4    6    8]
 [   8   10   18   80]
 [  50  100  150 5000]]
