I admit I worked hard at school, and learned quite a lot of maths over the years, and it suits my strengths, but…
I use mental arithmetic dozens of times a day in my work, in safety critical siuations. Speed and accuracy being important.
I use algebra regularly to solve everyday problems, because once the scenario is recast as an equation the result can easily be calculated and might be a surprise, something you might not come to with gut feeling or intuition, or experience. Although, admittedly while true, often not practical. The biggest skill I learned was how to extract the equation from the question!
I often find those who claim they never needed maths since school are simply those with no interest in the help that maths could give them!
