Very neat logo. I am a Mechanical Engineer, and I like the use of the variety of tools including the micrometer and vernier caliper is great. There is a symbol for the assassin order that is a measuring tool, I'll find it in my encyclopedia and post it for you. Well done.
For a calculator, use a slide rule or abacus, seems a bit more appropriate.

You can always make variations lol. The original Assassin's Creed symbol varies according to the country they're in. The games vary equally - like the first AC logo had a square shape in the middle of the "A", and AC4 has a skull on it (due to being about pirates).
There can always be a variant with a stylized calculator on the middle of the big "A" lol
