Calculation
A nice calculator (scientific). The side pad for writing is a nice touch. Took me a minute to work it out. Has a blotch on the screen so rubbed it with the pen ( was awkward trying to get the pen out) and then reset the screen clear. Calculator buttons as you’d expect and sin cos tan with a dot of Pi
