合には不必要である。(1) How to find divisors Taking the integer ``12'' as an example,
In this case, move the number board E and cursor F to A in Figure 2.
Hold it in your hand and move the cursor as shown, and stop the cursor F at the position where the number "12" appears in the vertical hole k as shown in FIG. 2B. In this state, look at the number "12" that appears in the vertical cursor hole k (in the case of the example, it appears in five places), and look at the number 2, 3, 4, 6 of the cursor integer number m located right next to it. By reading 12, the number divided by this reading and "1" are all divisors, that is, the divisors of 12 are "1,
2, 3, 4, 6, 12''. In addition, when calculating the divisor of an integer greater than or equal to 31 (for example, 35
When finding the divisor of ), a number will also appear in the vertically long hole k' on the back side of the cursor, as shown in FIG. 2C, so it is necessary to read the divisor corresponding to this number. However, this is necessary only in the configuration of the embodiment, and is unnecessary in the case of a number board configuration that can be read entirely on the front side.

(2) 倍数の見つけ方整数が「６」の場合を例にとつて説明すると、
この場合は前記数表板ＥとカーソルＦと第３図Ａ

る。(2) How to find multiples To explain the case where the integer is "6" as an example,
In this case, the number table E, the cursor F, and the figure A
Hold it in your hand and move cursor F from the left to the right. Then, while looking at the number “6” of the cursor integer number m,
Look at the numbers ``6, 12, 18...'' appearing in the corresponding positions in order as shown in Figure 3 B to D. By this, the multiples of the integer "6" up to 60 are "6, 12,
18, 24...60''.

(3) 公倍数の見つけ方整数が「４と６」の場合を例にとつて説明する

24，36，48，60」であることを求めることができ
る。(3) How to find the common multiple Let's take the case where the integers are 4 and 6 as an example. In this case, move the number board E and cursor F to the fourth
Hold it in your hand as shown in Figure A and move cursor F from the left edge to the right. Then, while looking at the numbers "4" and "6" of the cursor integer number m, select the numbers "12, 24, 36" that appear simultaneously in both the "4" and "6" corresponding positions of the cursor vertical hole k. . . .” in order as shown in FIG. 4 B to D. As a result, the common multiple of the integers "4 and 6" up to 60 is "12,
24, 36, 48, 60".

なお、30以下の数と31以上の数との組合わせの

は不必要である。 In addition, in the case of a combination of a number below 30 and a number above 31, it is necessary to look at both the front and back. However, this is necessary only in the configuration of the embodiment, and is unnecessary in the case of a number board configuration that can be read entirely on the front side.
