The Sum practice series was published alongside the “3 out of
6 = ½” Multi cache. It comprises a trail linking two
historically significant sites, the famous Stanley Ferry Aqueduct
and the Newland estate , which has a long history dating back to the Bronze
Age. As well as providing an interesting walk in its own right,
this series of 7 is designed to give you sum simple practice to
help solve the much more difficult sums involved in the Multi
cache.
Not all caches in the series have a pencil so bring your
own.
The walk is not dangerous in itself but does involve a short walk
on a road without a proper pavement, walking near a canal and a
river, walking near derelict buildings and, depending on the
weather and time of year, walking on some slippy muddy paths. As
such be mindful of young ones and wear appropriate footwear.
You can do the sums for this series at your leisure in the
warmth of your own home and check your answer in the hint. Although
the hint confirms the answer to the sum, only in the cache will you
find the letter which reveals where this number fits into the bonus
cache co-ordinates
Sum practice 6 is a magnetic key holder but don't read too much
into that. Please replace as found. Make a note of the letter at
the cache so you know what to do with the answer to the sum
below.
If A=1 and B=4 and C= 5 what is D?
2 x (A + {C x B}) / (C + A) = D
From this cache, to claim the bonus and head back towards the
starting point, you can follow your GPS to return the way you came
(latching on to the cache Sum practice 3 will get you back on
track) or you could alternatively latch on to the cache Altnew 2-
divert to bully and turn left along the road to complete a longer
circular walk. This circular way however would take you on the road
back to Stanley Ferry, parts of which have no pavement.
