    How can we calculate sig fig values during math class?

    A scientist can only attain a certain degree of accuracy when measuring anything, restricted either by the instruments used or by their physical nature. The clearest instance is range measurement. Consider how the range of an item passed by tape (in metric units) is being measured. The tape measurement is probably divided into the lowest millimeters. Therefore, you can’t measure more than a millimeter in accuracy. Therefore, if the object moves 57,215,493 mm, we are sure that it moved 57 mm (or, depending on the preference for that situation, 57.7 cm or 0,057 m). This rounding amount is usually OK in such kinds of examples. It would truly be a…
