Brain Game: Math Square #11

The nine white squares inside the main red grid should be filled with the digits 1 through 9. Each digit should appear only once in this main grid. Two of these numbers are already provided for you. Place the other digits in the correct spots so that the mathematical equations work both across and down. IMPORTANT: Remember algebraic rules when solving the problems... multiplication and division should be performed in the first step, then addition and subtraction in the second. Good luck!

A Very Brief History of Chamber Pots

Some of the oldest chamber pots found by archeologists have been discovered in ancient Greece, but portable toilets have come a long way since then. Whether referred to as "the Jordan" (possibly a reference to the river), "Oliver's Skull" (maybe a nod to Oliver Cromwell's perambulating cranium), or "the Looking Glass" (because doctors would examine urine for diagnosis), they were an essential fact of life in houses and on the road for centuries. In this video from the Wellcome Collection, Visitor Experience Assistant Rob Bidder discusses two 19th century chamber pots in the museum while offering a brief survey of the use of chamber pots in Britain (including why they were particularly useful in wartime).
