    Problems 17, 7B and 8–40 are concerned with arithmetic and elementary algebra. Problems 1–6 compute divisions of a certain number of loaves of bread by 10 men and record the outcome in unit fractions. Problems 7–20 show how to multiply the expressions 1 + 1/2 + 1/4 = 7/4, and 1 + 2/3 + 1/3 = 2 by different fractions.

    A ratio is often converted to a fraction when it is expressed as a ratio to the whole. In the above example, the ratio of yellow cars to all the cars on the lot is 4:12 or 1:3. We can convert these ratios to a fraction, and say that ⁠ 4 / 12 ⁠ of the cars or ⁠ 1 / 3 ⁠ of the cars in the lot are yellow.

    [7] Computations involving the R n,n (on the main diagonal) can be done quite efficiently. For example, R 3,3 reproduces the power series for the exponential function perfectly up through 1 / 720 z 6, but because of the symmetry of the two cubic polynomials, a very fast evaluation algorithm can be devised.

    However, 1 is a square mod 3 (equal to the square of both 1 and 2 mod 3), so there can be no similar identity for all values of that are congruent to 1 mod 3. More generally, as 1 is a square mod n {\displaystyle n} for all n > 1 {\displaystyle n>1} , there can be no complete covering system of modular identities for all n {\displaystyle n ...
