Numbers 1‚ 2‚ 3…….‚ which are used for counting are called Natural numbers and are denoted by N. 0 when included with the natural numbers form a new set of numbers called Whole number denoted by W -1‚-2‚-3……………..- are the negative of natural numbers. The negative of natural numbers‚ 0 and the natural number together constitutes integers denoted by Z. The numbers which can be represented in the form of p/q where

Higher Arithmetic Higher arithmetic‚ also known as the theory of numbers‚ is known for its basics of the natural numbers‚ simple numbers. The numbers‚ 1‚ 2‚ and 3 are numbers that are known as natural numbers. H. Davenport of Cambridge University once said “…in all the records of ancient civilizations there is evidence of some preoccupation with arithmetic over and above the needs of everyday life” (Introduction). The theory of numbers being a science‚ is simply just a creation invented for the

the formulas: a3 + b3 = (a + b)(a2 – ab + b2) a3 – b3 = (a – b)(a2 + ab + b2) You’ll learn in more advanced classes how they came up with these formulas. For now‚ just memorize them. First‚ notice that the terms in each factorization are the same; then notice that each formula has only one "minus" sign. For the difference of cubes‚ the "minus" sign goes with the linear factor‚ a – b; for the sum of cubes‚ the "minus" sign goes in the quadratic factor‚ a2 – ab + b2. Some people use the mnemonic "SOAP"
