Basic ConceptsOpposites of numbers; opposite numbers have opposite signs (negative and positive) Reciprocals of numbers: reciprocal of n=1/n , reciprocal of a/b=b/aAbsolute values of numbers: REMOVE THE SIGN, |n|=n, |-n|=nOrder of operations: PEMDAS; Parenthesis, Exponents, Multiplication&Division, Addition&SubtractionRadicals::Sets: {1, 2, 3, 4, 5, 6, 7, 8, 9}Listing the elements explicitly like this, instead of using a rule, is often called "using the roster method".{xis a natural number,x< 10} ? Rule methodExponents:a^m x a^n = a^(m+n)a^(b/c)= a to the power of b and to the c root(a^m)^n=a^(mxn)a^0=1, as long as a is not equal to 0a^-m=1/(a^m)Equations:Linear equations0 = 0 means solution is all real numbers0 = something other than 0 means no solutionAbsolute value equations| X | = p, where p is positive is equivalent to solving X = -p or X =p.
