Raising a number to the square called constructionof the second degree. In general, the construction of the power? one of algebraic operations that cause difficulty in understanding and implementation of the calculation.
Nevertheless, the need of squaring occurs in many mathematical and practical problems.
Thus, in order to raise the number of square, It is necessary to multiply it by itself. At the same mathematical notation of action is as follows:
a2 = a * a.
To build in square small enough numbers multiplication tables. To build in square double-digit numbers and more, require a calculator or computer.
