Instructions for use
In the "Calculation Formula" column of the Luban Calculation Book, calculation formulas can be entered, and the calculation results are placed in the "Calculation Result" column. In the "Result Variable" column, the variable name representing the calculation result can be entered. Addition, subtraction, multiplication, and division can be used in the calculation formula. Four arithmetic operations such as brackets (only parentheses can be used for brackets), and can be applied at multiple levels; variable names can also be used in calculation formulas. Variable names can only start with letters and can contain letters and numbers. Variable names are not case-sensitive. Multiple identical variables can appear in the same calculation book. If multiple identical variables appear, the variable in the calculation formula is the closest one (from the first row downward).
