question: In Tate’s garden pond, there are 4 male guppies, 7 female guppies, 3 male goldfishes, and 5 female goldfishes.  He buys 2 male guppies, 1 female guppy, 2 male goldfishes, and 3 female goldfishes.  How many more female fishes than male fishes does Tate have?
answer: Tate has a total of 4 + 3 = <<4+3=7>>7 male fishes.
  He has a total of 7 + 5 = <<7+5=12>>12 female fishes.
  After the purchases, he has 7 + 2 + 2 = <<7+2+2=11>>11 male fishes.
  After the purchases, he has 12 + 1 + 3 = <<12+1+3=16>>16 female fishes.
  In his pond, there are this many more female fishes than male fishes 16 - 11 = <<16-11=5>>5 fishes.
