Every line, explained
print(7 + 3)- + adds two numbers together.
print(7 - 3)- - subtracts the right number from the left one.
print(7 * 3)- * means multiply: there is no × key on a keyboard, so programmers use the asterisk.
print(7 / 2)- / means divide. Notice the answer: 3.5. In Python, dividing always gives a decimal answer, even when it divides evenly; 8 / 2 would print 4.0.
