NumPy: Add, subtract, multiply, divide arguments element-wise

NumPy Mathematics: Exercise-1 with Solution

Write a NumPy program to add, subtract, multiply, divide arguments element-wise.
Sample elements: 4.0, 1.2

Sample Solution:

Python Code:

# Importing the NumPy library
import numpy as np

# Displaying a message for addition operation
print("Add:")
# Performing addition
print(np.add(1.0, 4.0))

# Displaying a message for subtraction operation
print("Subtract:")
# Performing subtraction
print(np.subtract(1.0, 4.0))

# Displaying a message for multiplication operation
print("Multiply:")
# Performing multiplication
print(np.multiply(1.0, 4.0))

# Displaying a message for division operation
print("Divide:")
# Performing division
print(np.divide(1.0, 4.0))

Sample Output:

Add:                                                                   
5.0                                                                    
Subtract:                                                              
-3.0                                                                   
Multiply:                                                              
4.0                                                                    
Divide:                                                                
0.25  

Explanation:

In the above exercise –

np.add(1.0, 4.0): Here NumPy's add() function is used to add the two numbers together, which in this case are 1.0 and 4.0. The result would be 5.0.

np.subtract(1.0, 4.0): Here NumPy's subtract() function is used to subtract the second number from the first one, which in this case are 1.0 and 4.0 respectively. The result would be -3.0.

np.multiply(1.0, 4.0): Here NumPy's multiply() function is used to multiply the two numbers together, which in this case are 1.0 and 4.0. The result would be 4.0.

np.divide(1.0, 4.0): Here NumPy's divide() function is used to divide the first number by the second one, which in this case are 1.0 and 4.0 respectively. The result would be 0.25.
