Excerpt: This Canon calculator is fantastic. It is powered by batteries and solar panel and is simple to operate. There are many functions including a number of memories, they are labelled as A, B, C, D, M (Memory) and X and Y. The X and Y are probably really useful for GCSE and A-Levels since everything seems to revolve around X and Y in those questions!
Pros: Easy to use, can edit lines, remembers history, suitable for GCSE
