Bug report

[Carla Molina]

I found the following bug (python 3.9.1) when multiplying an array by
several variables without parentheses; look at the following example:

import numpy as np

NR = 0.25
N = 60461826

initialINCIDENCE = np.array([1, 50, 100, 150, 200, 250, 300])
initialINCIDENCE = initialINCIDENCE*N/(100000*7*NR)
print('First result ' +str(initialINCIDENCE))

initialINCIDENCE = np.array([1, 50, 100, 150, 200, 250, 300])
initialINCIDENCE = initialINCIDENCE*(N/(100000*7*NR))
print('Second result ' +str(initialINCIDENCE))

The result given is:

First result [   345.49614857  -7267.86283429  10006.94459429   2739.08176
  -4528.78107429 -11796.64390857   5478.16352   ]
Second result [   345.49614857  17274.80742857  34549.61485714
 51824.42228571  69099.22971429  86374.03714286 103648.84457143]

Clearly both are different, and in particular the first one has no sense to
me.
Thank you,

Carla.
