In a corporate budget report, when an analyst subtracts the actual expenses ($e$) from the projected budget ($b$), the result of the calculation $b - e$ is mathematically known as the ____.

An HVAC technician is measuring the pressure drop across an air filter to determine if it needs replacement. They record the intake pressure as ${}24$ psi and the output pressure as ${}22$ psi. The technician calculates the drop using the expression ${}24 - 22$ and finds a result of 2 psi. Which mathematical term specifically describes the result of this subtraction?

In a corporate financial audit, if an analyst calculates the budget variance by subtracting the total expenses ($e$) from the gross revenue ($r$), the numerical result of the operation $r - e$ is mathematically defined as the 'difference'.
