I was first introduced to algebra during the final few weeks of Primary School, and remember approaching the subject with a distinctive lack of enthusiasm!
However, it was very much a case of just having to come to grips with the matter, particularly when deciding to learn the electrical trade. Take for example Ohm's Law, E = I.R. which is arguably the most fundamental calculation for electrical circuits.
Once you encounter three-phase systems, it starts getting more involved; to calculate the power in a three-phase circuit the formula is P=√3.V.I.CosՓ
Then, if ever involved with Electrical Test Work, it gets more involved again; an example being Wenner's Equation for calculating soil resistivity (a project our team is embarking on next week)
I have been engaged in Electrical Testing since 1980, and can vouch for the fact that this field of the electrical trade calls for both the use of algebra, and a readiness to get ones "hands dirty".
A good example of that is the project that I have just come back from, which was testing the protection relays at a manganese mine in northern Australia. At that site, everything is liberally coated in a sticky black dust from off the manganese ore. Not the sort of job you front up to in a white shirt, tie and three-piece suit!
