^{7}According to calculus convention, the differential dt represents the end of the integrand. It is safe to
regard the long āSā symbol and the differential (dx, dt, etc.) as complementary grouping symbols declaring the
beginning and end of the integrand. This tells us m_{0} is not part of the integrand, but rather comes after it.
Using parentheses to explicitly declare the boundaries of the integrand, we may re-write the expression as
m_{x} = (ā«
_{0}^{x}W dt) + m_{0}
