In the introduction, the situations that should require the use of a calculator are:

multiplying a multi-digit number by itself several times (finding the power of a number)

finding a square root

ordinary arithmetic

statistical calculations

multiplying a multi-digit number by itself several times (finding the power of a number) finding a square root statistical calculations

Step-by-step explanation:

We don't know what your introduction tells you, but the above-listed operations are ones I choose to use a calculator for. I also use a calculator for ordinary arithmetic, such as division by numbers with 2 digits or more. (It is simply faster and requires no scratch paper.)

If statistical calculations are not done with a calculator, they at least require the availability of suitable tables.

___

All of these operations can be done by hand without a calculator, and were in times passed. Lifetimes of effort were involved in generating some of the original math tables for statistics, trig, logarithms, and other functions readily evaluated using a modern calculator.
