The online service Math XL is used for multiple purposes in education. It is used as a tutorial device for students to help them learn, a testing device for students to assess their knowledge, and as a lesson planning device to aid teachers.
A device to aid lift, such as Slats and Flaps on the wings.
A camera lucida device is used by artists as a drawing aid. A camera lucida is used to superimpose the image of an object onto a drawing surface so the artist can recreate the image.
A Mnemonic Device is an aid to memory and recall. It can be a word, a phrase, an anagram, a picture, a string around your finger. A famous one is "ROYGBIV" to remember the colors in the visible spectrum, and their order from long wavelength to short. Red, Orange, Yellow, Green, Blue, Indigo, Violet.
I would not call the MS suite a Multimedia aid although the programs could be used to generate multimedia content.
