... Solution. There are four possibilities where the photographed I-C-C carriage sequence can be, and for each of them there are 23 ways to complete the train. However, this results in counting the train I-C-C-I-C-C twice. Thus the number of different trains is 4 · 8 − 1 = 31. Problem 13J / 3S. An obje ...

THE NEW AC METHOD TO FACTOR TRINOMIALS.
... Solution. The numbers p and q have different signs (since a and c have different signs). Compose factor pairs of (c = -102) with all first numbers being negative. Proceed: (-1, 102)(-2, 51)(-3, 34)(6, 17). The last sum is: (-6 + 17) = 11 = -b. By changing to the opposite (-b b), we then get: p = 6 ...

Elementary arithmetic
Elementary arithmetic is the simplified portion of arithmetic that includes the operations of addition, subtraction, multiplication, and division. It should not be confused with elementary function arithmetic.Elementary arithmetic starts with the natural numbers and the written symbols (digits) that represent them. The process for combining a pair of these numbers with the four basic operations traditionally relies on memorized results for small values of numbers, including the contents of a multiplication table to assist with multiplication and division.Elementary arithmetic also includes fractions and negative numbers, which can be represented on a number line.
