Here you go smarties!! The answers to the practice problems!!  Did you get all of them right? Hopefully you all did!!

1) -9  +   ( 33  +  -42 ) = -9 + (-9)                                                               2) -60  ÷  4  +  14 = -15 + 14
                                   = -18                                                                                                    = -1
 

3) 31  +   ( 41  -  43  ×  12 ) = 31 + (41 - 516)                                             4) 22  +  13  +  22  ×  45 = 22 + 13 + 990
                                           = 31 + -475                                                                                            = 35 + 990
                                           = -444                                                                                                    = 1025

5) 43  + 147  ÷  49  +  2 = 43 + 3 + 2                                                         6) 84  ÷  6  ×  -2 = 14 x -2
                                      = 46 + 2                                                                                          = -28
                                      = 48

7) 38  +   ( 30  ÷  10 )   -  26 = 38 + (3) - 26                                                8) 46  +  22  -  -8  +  -6 = 68 - -8 + -6
                                            = 41 - 26                                                                                              = 76 + -6
                                            = 15                                                                                                     = 70

9) -41  +  22  -  22  -  4  +  211 = -19 + 22 - 22 - 3 + 21
                                               = 3 -22 - 3 + 21
                                               = -19 - 3 + 21
                                               = -22 + 21
                                               = -1

10) 28  +  46  +  -3  +  42  ×  -6 = 28 + 46 + -3 + -252
                                                  = 74 + -3 + -252
                                                  = 71 + -252
                                                  = -181
