1 bag of cement requires 4 gallons of water and covers 20 sq feet. I need 500 square feet so how much water do I need?
Algebra is the ability to reorganize, and combine formulas to solve for x.... in this case water.

Most construction workers doing anything other than pure manual labor likely use some form of algebra on the job.

Even pure labor guys likely do something like. Boss said we need to get the drywall on this floor down today. It took us 3 hours to do these 2 wall (estimate at 30% of the room) and we have a 9 hour workday so.... <some algebra later> yup looks like we are on track to finish, lets take a 5 minutes smoke break.

Most algebra is done in your head however the fundamentals in Algebrea class develop the ability to do it in your head.
