This calculator has two memory allocations: independent
memory (M), and last answer memory (ANS). You will find
them especially useful when combinations of calculations
become complicated, or when using the answer of previous
calculation to another operations.

Do not carry the calculator around in your back pocket, as
it may break when you sit down. The display is made of
glass and is particularly fragile.
Keep the calculator away from extreme heat such as on a
car dashboard or near a heater, and avoid exposing it to
excessively humid or dusty environments.
Since this product is not waterproof, do not use it or store
it where fluids, for example water, can splash onto it.
Raindrops, water spray, juice, coffee, steam, perspiration,
etc., will also cause malfunction.
