- Simple Division
- There is a simple division sum.
- Can you restore it by substituting a figure for every asterisk, without altering or removing the sevens?
- If you start out with the assumption that all the sevens are given, and that you must not use another,
- It is comparatively easy.
**7** ----------- ****7*)**7******* ****** ------- *****7* ******* ------- *7**** *7**** ------- ******* ***7** -------- ****** ****** ------
