Formulas must be numbered with Arabic numerals in sequential order within each chapter. The first digit indicates the chapter number, and the second digit represents the formula’s order within that chapter. Formulas must be centered, and their numbering must be placed at the end of the formula line, aligned to the right.

Explanations of the symbols and coefficients used in the formulas must be presented below the formula, in the same order as they appear within the formula.

All formulas must be referenced in the text, and each formula must be placed immediately after its first mention.

Example:
According to formula (1.1), the calculation is performed as follows:

 Ax + B = C       (1.1)
