Algebra

ALGEBRA REPORT Algebra is a branch of mathematics in which letters are used to represent basic arithmetic relations. As in arithmetic, the basic operations of algebra are addition, subtraction, multiplication, division, and the extraction of roots. Arithmetic cannot generalize mathematical relations such as the Pythagorean theorem: which states that the sum of the squares of the sides of any right triangle is also a square. Arithmetic can only produce specific instances of these relations (for …

…an upside down U. Empty set-no members common to both sets. Union-The set of all members that are equal to both A and B. Use a U to show the union. Conjunction- x>5 and x<12. Use and two statements. Disjunction- x<-3 or x>6. Using OR Half-planes- regions above and below the line. Boundry line- The line that it forms System of inequalities- 2 or more linear inequalities for which is a common solution is sought.
