TeX (original user input):

 \begin{align}
\text{specificity} & = \frac{\text{number of true negatives}}{\text{number of true negatives} + \text{number of false positives}} \\ \\ & = \frac{\text{number of true negatives}}{\text{total number of well individuals in population}} \\  \\
& = \text{probability of a negative test given that the patient is well}
\end{align}

TeX (checked):

{\begin{aligned}{\text{specificity}}&={\frac {\text{number of true negatives}}{{\text{number of true negatives}}+{\text{number of false positives}}}}\\\\&={\frac {\text{number of true negatives}}{\text{total number of well individuals in population}}}\\\\&={\text{probability of a negative test given that the patient is well}}\end{aligned}}
