Cycles of the unit digit of multiples of integers ending in 1, 3, 7 and 9 (upper row), and 2, 4, 6 and 8 (lower row) on a telephone keypad. Figure 1 is used for multiples of 1, 3, 7, and 9. Figure 2 is used for the multiples of 2, 4, 6, and 8. These patterns can be used to memorize the multiples of any number from 0 to 10, except 5.
The following table shows a Relay and Bye Stand Mitchell for eight tables with Table 2 and Table 3 sharing one group of boards and the bye stand between Table 6 and Table 7 (which, with eight tables, are directly opposite Table 2 and Table 3, respectively, in the rotation).
V2: Does pupil (p) know the (1-10) multiplication table? No=1; Yes=2. V3: Can pupil (p) perform multiplication of numbers? No=1; Yes, but only of two-digit numbers=2; Yes=3. V4: Can pupil (p) perform long division? No=1; Yes=2. Data collected for the above four variables among a population of school children may be hypothesized to exhibit the ...
From the Bernegger table: sin (75° 10′) = 0.9666746 sin (75° 9′) = 0.9666001. The difference between these values is 0.0000745. Since there are 60 seconds in a minute of arc, we multiply the difference by 50/60 to get a correction of (50/60)*0.0000745 ≈ 0.0000621; and then add that correction to sin (75° 9′) to get :
3 1 / 9 1 / 10 2, 5: 0.1: 0.2: 2, 5 ... This table shows the Maya numerals and the number names in Yucatec Maya, Nahuatl in modern orthography and in ...
The group {1, −1} above and the cyclic group of order 3 under ordinary multiplication are both examples of abelian groups, and inspection of the symmetry of their Cayley tables verifies this. In contrast, the smallest non-abelian group, the dihedral group of order 6, does not have a symmetric Cayley table.
The Rhind Mathematical Papyrus, [1] [2] an ancient Egyptian mathematical work, includes a mathematical table for converting rational numbers of the form 2/n into Egyptian fractions (sums of distinct unit fractions), the form the Egyptians used to write fractional numbers. The text describes the representation of 50 rational numbers.
This is an injective relation: each combination of the values of the headers row (row 0, for lack of a better term) and the headers column (column 0 for lack of a better term) is related to a unique cell in the table: Column 1 and row 1 will only correspond to cell (1,1); Column 1 and row 2 will only correspond to cell (2,1) etc.
