There are 6 + 9 = <<6+9=15>>15 knives
There are 15 x 2 = <<15*2=30>>30 spoons
There are 6 / 2 = <<6/2=3>>3 teaspoons
There are 6 + 15 + 30 + 3 = <<6+15+30+3=54>>54 pieces before adding more cutlery.
2 of each 4 types of cutlery are added, and therefore 2 x 4 = <<2*4=8>>8 pieces added.
In total there are 54 + 8 = <<54+8=62>>62 pieces of cutlery in the drawer
