FIG. 5 is a plan view of the same piece of paper as viewed from the opposite direction, FIG. 5 is a perspective view showing a use state when a right-handed person flips with his left hand, and FIG. 6 is a perspective view of a left-handed person flipping with his right hand. It is a perspective view showing a use state.

[0008] The slip calculation problem collection 1 includes a sheet 2 as in the conventional example.
Are formed by closing a plurality of sheets 2, 2,..., And as shown in FIG. Therefore, when this is viewed from the back cover 1B side as shown in FIG. 2, the closing portion 3 is located at the upper right corner B. The closing part 3 is formed by a stapler needle.

The paper pieces 2, 2, 2,... Are, as shown in FIG. 3 and FIG.
B are printed with five-stage numbers 4, 4, 4,... As for the numeral 4, the same numeral is sequentially displayed in the same order from the forward direction (when viewed from the front cover 1A side) and the reverse direction (when viewed from the back cover 1B side). That is, the same numeral 4 is printed on both front and back surfaces 2A and 2B of the same page counted from the forward direction and the reverse direction.

Further, each of the above-mentioned paper pieces 2, 2, 2,...
As shown in FIGS. 3 and 4, both front and back surfaces 2A, 2B
, The same number of pages 5 in the same order from the forward direction (when viewed from the front cover 1A side) and the reverse direction (when viewed from the back cover 1B side) in the order of 1, 2, 3,. Is displayed.

Next, a description will be given of a case where the operation of the present invention having the above configuration is calculated by using a calculator such as an electric desk calculator or an abacus.

First, in the case of a right-handed person, cover 1
The slip calculation problem book 1 is arranged with the A side as a table, that is,
The closing part 3 is positioned at the upper left corner A (see FIG. 5). In this state, the lower right corner a on the diagonally opposite side to the closing part 3 is gripped by the left hand, and the paper sheet 2 is rotated by the left arm.
