(1) Just set a few codes, write the same code for the same project, and distinguish them. You can use abcd, etc.
② Then enter SUM(abcd ...) to change a line in the formula, and the code you want to count is in brackets.
Extended data
First, the basic introduction of Corey calculation book
Corey calculation book is a general calculation book, which can solve the functions of calculation, statistics, reports and so on in engineering quantity calculation.
① In the table, you can enter an expression in the column of "Calculation Formula" and a variable name representing the calculation result in the column of "Code". The calculation results are placed in the rightmost "Results" column. Four operations such as addition, subtraction, multiplication, division and parentheses can be used in the expression, and parentheses can only be used in multiple layers.
(2) 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 case-sensitive. Multiple identical variables can appear in the same calculation book. If multiple identical variables appear, the variable in the calculation formula takes the closest one.
③ The leftmost graph is used to calculate the shape of an object. At present, this part has not been completed, and we will improve it in the new version soon. Press the left mouse button and drag up and down to select multiple lines. For multi-line operations, press the right mouse button, such as copy and code filling. After selecting multiple lines, press Ctrl+D to perform code filling.
