AV Math Fundamentals

The sums this trade actually asks for, worked the way the job needs them

Nobody goes into AV to do maths, and almost everybody in AV does maths every day. How many amps the rack will draw. How many panels make a six metre wall, and what they weigh. How far back the projector goes. How much delay the second loudspeaker tower needs. Whether a two terabyte drive will hold a three-day conference.
