Plain 8-digit calculator with memory
and the percentage operation. Its buttons need to be pressed
firmly and have a wonderful click. Its LED display is magnified
making it clearly readable. The numbers 9 and 6 are shown in a
particular way. The 9 misses its bottom segment, the 6 misses its
upper segment. Cloud this be to save a tiny little bit of battery
power?
