How did the computer get this answer!? >>> x = 2 >>> print(x) 2 >>> x += 3 >>> print(x) 5

x += 3 is shorthand for x = x + 3
Note that mathematically this wouldn't make sense, but in this case the equals sign is an assignment operator, and not an equality sign which is == in most programming languages.

ok x ends up = 5 because
firstly
you have set x = 2 so now x has the value of 2
as shown by printing it
when you do x + = 3
short for x = x + 3
which when you substitute the value of x in is
x = 2 + 3
which gives you the answer 5
