[docs] [issue30361] Docs example: converting mixed types to floating point

[Mihai Borobocea]

New submission from Mihai Borobocea:

Section 3.1.1 in the Docs states:
"operators with mixed type operands convert the integer operand to floating point"
https://docs.python.org/3/tutorial/introduction.html

But gives an example using the division operator:
>>> 3 * 3.75 / 1.5
7.5
>>> 7.0 / 2
3.5

In Python 3, division always returns a float, e.g. when all operands are integers:
>>> 3 * 3 / 1
9.0
>>> 7 / 2
3.5

To illustrate that "operators with mixed type operands convert the integer operand to floating point" the example should not use division. For example:
>>> 3 * 3.75 - 1
10.25
>>> 7.0 + 2
9.0
