Tk nha!

                 100 + 56 = 156

                  350 + 100 = 450

                 500 - 500 = 0

                100 - 50 = 50

100+1000:100+500

=100+10+500

=110+500

=610

150+500:5

=150+100

=250

100 + 1000 : 100 + 500 = 100 + 10 + 500

                                      = 610

150 + 500 : 5 = 150 + 100

                      = 250

goodluck!!
