Introduction I. Number Systems in Mathematics: A Number system (or system of numeration) is a writing system for expressing numbers‚ that is a mathematical notation for representing number of a given set‚ using graphemes or symbols in a consistent manner. It can be seen as the context that allows the symbols "11" to be interpreted as the binary symbol for three‚ the decimal symbol for eleven‚ or a symbol for other numbers in different bases. Ideally‚ a number system will: * Represent a

Complex Numbers All complex numbers consist of a real and imaginary part. The imaginary part is a multiple of i (where i =[pic] ). We often use the letter ‘z’ to represent a complex number eg. z = 3 +5i The conjugate of z is written as z* or [pic] If z1 = a + bi then the conjugate of z (z* ) = a – bi Similarly if z2 = x – yi then the conjugate z2* = x + yi z z* will always be real (as i2 = -1) For two expressions containing complex numbers to be equal‚

Learning is not only an essential skill to survive‚ it is also a requirement to attain a fulfilled life. Yet the public education system‚ where the majority of people are expected to learn‚ often overlook the process of learning. It is no wonder why one of the most accomplished thinkers‚ Albert Einstein‚ has said‚ “the only thing that interferes with my learning is my education” (qtd. In Silber 130). This quote embodies the current state of public education in the United States; a system that approaches

polyatomic ions). 1. Determine the Number of valence electrons in the Lewis Structure: One of the easiest ways to start drawing a Lewis Structure is to make a list of each atom in the structure and next to each atom record how many valence electrons it has and how many it needs to fill its valence shell. In covalent bonding the valence electrons in the molecule come from the valence electrons in the atoms that formed the bond. a. The number of valence electrons in any main group atom

Section 4.1 Divisibility and Modular Arithmetic 87 CHAPTER 4 Number Theory and Cryptography SECTION 4.1 Divisibility and Modular Arithmetic 2. a) 1 | a since a = 1 · a. b) a | 0 since 0 = a · 0. 4. Suppose a | b ‚ so that b = at for some t ‚ and b | c‚ so that c = bs for some s. Then substituting the first equation into the second‚ we obtain c = (at)s = a(ts). This means that a | c‚ as desired. 6. Under the hypotheses‚ we have c = as and d = bt for some s and t . Multiplying

(i) It is evident that 1‚ 2‚ 3‚ and 4 are the only natural numbers less than . Thus‚ when x is a natural number‚ the solutions of the given inequality are 1‚ 2‚ 3‚ and 4. Hence‚ in this case‚ the solution set is {1‚ 2‚ 3‚ 4}. (ii) The integers less than are …–3

concern on the minds of the drivers. Many people die every year due to reckless or careless driving. Driving safe is not a choice it is the law‚ but the law is broken and people suffer the affects of it. Driving drunk and texting while driving is the number one killer while in a vehicle. My perspective before turning sixteen was to drive with out any worries‚ but now because of the incident with my mother I realize driving safe is the right thing to do.
