import numpy as np

# Adding a constant to the array

# Subtracting a constant from the array

# Multiplying the array by a constant

# Dividing the array by a constant

# Element-wise operations between two arrays

# Adding two arrays element-wise

# Dividing two arrays element-wise

# Dot product of two arrays
dot_product = np.dot(arr, arr2)
