STEPS FOR SPECIAL SYMBOL PROBLEMS

1) Write down the operation (uses variables)                                               x œ y = (x + y) (x – y)
2) Write down the example, with the symbols aligned                                 3 œ 2 = ?
3) Identify the value of the variables                                                               x = 3; y = 2
4) Plug in the values                                                                                        (x + y) (x – y) --> (3 + 2) (3 – 2)
5) Solve the resulting equation                                                                       (5)(1) = 5

SAMPLE PRACTICE QUESTION FOR SPECIAL SYMBOLS

1. Let the operation a † b be defined by a † b = (a + b)(ab) when a ≠ 0 and b ≠ 0. What is the value of 4†3?

     Solution
     1) Write down the information, symbols aligned.
     2) a † b = (a + b)(ab)
         4 + 3 = ?
     3) Substitute the proper values.
     4) 4 † 3 = (4 + 3) (4 3)
                   = (7)(12) = 84
