Problem Statement

Cut off a square carton by a straight line into two pieces, then cut one of two pieces into two small pieces by a straight line, ect. By cutting 20172017 times we obtain 20182018 pieces. We write number 22 in every triangle, number 1 in every quadrilateral, and 00 in the polygons. Is the sum of all inserted numbers always greater than 20172017?
