A quality control technician is measuring the deviation of a precision part from its target thickness. The initial measurement shows a deviation of $-5.123$ mm. After a calibration adjustment, the part deviates by an additional $-18.47$ mm. What is the total combined deviation from the target thickness?

A laboratory technician is recording consecutive decreases in the volume of a chemical solution. The adjustments are -5.123 mL and -18.47 mL. To determine the total change in volume, the technician must evaluate the expression -5.123 - 18.47. Arrange the following steps in the correct order to perform this calculation using the standard decimal procedure.

A civil engineer is calculating the total settlement of a bridge pier after two recorded shifts in the soil, measured as -5.123 cm and -18.47 cm. True or False: To evaluate the total settlement using the expression $-5.123 - 18.47$, the engineer should align the decimal points and add 5.123 to 18.470, then apply a negative sign to the resulting sum.

An analyst is evaluating the expression $-5.123 - 18.47$ to determine the total net change in a financial ledger. Match each component of the calculation to its specific purpose or result according to the standard evaluation procedure.
