You can change any of these settings above. Press "New problems" for a fresh set with the same settings, or pick Version A to Z to print different sheets for neighboring desks. The answer key always matches.
Choose expressions with the four operations only, with brackets, with exponents (squares and cubes), or with both brackets and exponents. Any brackets in an expression really change the answer, and in the plain four-operation expressions reading left to right gives a different answer. Every step comes out as a whole number of at least 2, so nothing is trivial.
Expressions never divide by something and then multiply without brackets, so there is only one reasonable value for each one. The solved example works through the steps one at a time and names each step, and the answer key gives the final value.
