# You can add operators yourself, using the operators argument, but these are the defaults:
# +----+---------------------------------------------------------------------------------+
# | +  | add two things. x + y 1 + 1 -> 2                                                |
# +----+---------------------------------------------------------------------------------+
# | -  | subtract two things x - y 100 - 1 -> 99                                         |
# +----+---------------------------------------------------------------------------------+
# | /  | divide one thing by another x / y 2/3 -> 0.6666666666666666                     |
# +----+---------------------------------------------------------------------------------+
# | // | divide one thing by another x // y 2//3 -> 0                                    |
# +----+---------------------------------------------------------------------------------+
# | *  | multiple one thing by another x * y 10 * 10 -> 100                              |
# +----+---------------------------------------------------------------------------------+
# | ** | 'to the power of' x**y 2 ** 10 -> 1024                                          |
# +----+---------------------------------------------------------------------------------+
# | %  | modulus. (remainder) x % y 15 % 4 -> 3                                          |
# +----+---------------------------------------------------------------------------------+
# | == | equals x == y 15 == 4 -> False                                                  |
# +----+---------------------------------------------------------------------------------+
# | != | not equals x != y 15 != 4 -> True                                               |
# +----+---------------------------------------------------------------------------------+
# | <  | Less than. x < y 1 < 4 -> True                                                  |
# +----+---------------------------------------------------------------------------------+
# | >  | Greater than. x > y 1 > 4 -> False                                              |
# +----+---------------------------------------------------------------------------------+
# | <= | Less than or Equal to. x <= y 1 <= 4 -> True                                    |
# +----+---------------------------------------------------------------------------------+
# | >= | Greater or Equal to x >= 21 1 >= 4 -> False                                     |
# +----+---------------------------------------------------------------------------------+
# | in | is something contained within something else. "spam" in "my breakfast" -> False |
