Not sure if you’re joking, but not only Algebra but a whole host of subjects are very useful in life. Just not all the time and in ways that cannot be anticipated.
Electricians never needed geometry before. Now (I’m told) those principles are applied daily in their work. A decade or two ago math was thought by them as ‘useless’. Today they need to know it to keep their job.
Not to mention mastering various levels of mathematics sharpens one’s thinking.
Kinda joking. I know certain jobs use algebra and I guess you could even possibly use it in some scenarios for getting christmas gifts
For example: John wants to spend 200 dollars on gifts for 3 family members and 2 friends. Family members will have double the money spent
X = 3 + X=2 = 200
50(3) + 25(2) = 200 dollars.
150+50=200 dollars
I guess you could do something like that in your daily life.
