Calculus is a mathematical technique: it is not a unit or tool for measurement.
The measurement tool called a compass (a divider caliper, two rods on a hinge) is used for drafting and for measurement of arc distances. It may be considered to be a tool of mathematics, particularly geometry.The navigational tool called a compass (magnetic compass) determines direction based on the heading compared to the direction of the magnetic north pole and is not likely to be considered to be a tool of mathematics.

Significant figures represent the precision of a measurement because they indicate the level of uncertainty in a measurement due to the limitations of the measuring tool used. Accuracy, on the other hand, refers to how close a measured value is to the true value. The number of significant figures does not necessarily reflect the accuracy of a measurement, as a measurement can be precise (consistent) but not accurate (close to the true value).
The precision of a measurement can be determined by looking at the number of decimal places in the measurement. The more decimal places, the more precise the measurement. Additionally, if a measuring tool is capable of measuring smaller increments, it can provide a more precise measurement.
To find the least precision, look for the smallest increment or smallest degree of accuracy in the measurement tool or system being used. This is usually the smallest unit of measurement that the tool can detect or the smallest change that the system can register. Identifying the least precision helps in understanding the level of detail or accuracy that can be reliably obtained from the measurement.
A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.
Uncertainty in a measuring tool is typically determined by factors such as calibration, precision, and the manufacturer's specifications. It is quantified by calculating the margin of error or the range within which the true value is likely to lie. This information is often provided by the manufacturer and can be used to determine the precision of the measurements obtained with the tool.
Significant figures are a way to communicate the precision of a measurement, showing the level of certainty in a number. They indicate the known digits in a measurement plus one estimated digit. Accuracy, on the other hand, refers to how close a measurement is to the true value, which can be affected by systematic errors that can't be corrected by considering significant figures.

Significant figures are important because they indicate the precision of a measurement. They help convey the uncertainty in a measurement and ensure that the reported value reflects the limitations of the measuring tool. Using the correct number of significant figures also promotes consistency and accuracy in scientific communication.
Validity is the extent to which a measurement tool actually measures what we wish to measure.
The accuracy of a measurement is determined by how closely the measured value corresponds to the true value of the quantity being measured. Factors that can affect accuracy include the precision of the measuring tool, human error, calibration of instruments, and systematic errors in the measurement process.
A thumb gauge is a tool used for measuring distances or thicknesses. It typically consists of a sliding mechanism that is adjusted using one's thumb to determine the measurement. Thumb gauges are commonly used in woodworking and crafting for precision measuring.
