We all use basic arithmetic (+ - / *) in everyday life, and reading powers and scientific notation is useful for things like programming and reading some national geographic magazines and what not. The Pythagorean theorem is useful for some things. But I don’t understand how quadratic equations, calculus, radical expressions, sequences/series, and imaginary and complex numbers are used in everyday life. What are some REAL, USEFUL applications of these things?

mass. To convert from one to the other you will need to know what
material is being converted and what temperature it is at. There is
no universal conversion from gallons to kilograms.
We need the density of the substance to convert.
Gallons are a measure of volume; kilogram is a measure of
mass.
Assuming water:
1 kg = 1 liter = 0.264172052 US gallons = 0.219969157 imperial
