Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Jess made 3 different stacks of wooden blocks. The first stack was 7 blocks high, the second stack was 5 block(s) higher than the first, and the final stack was 7 block(s) higher than the second. Jess’ little sister knocked over the entire first tower, in the second tower she left 2 blocks standing, and in the final tower she left 3 blocks standing.  How many blocks in total fell down?

### Response:
 Mfungu wa kwanza: 7 vitalu
Vilivyopinduliwa: 7 vitalu
Mfungu wa pili: 7 + 5 = <<7+5=12>>12 vitalu
Vilivyopinduliwa: 12 - 2 = <<12-2=10>>10 vitalu
Mfungu wa mwisho: 12 + 7 = <<12+7=19>>19 vitalu
Vilivyopinduliwa: 19 - 3 = <<19-3=16>>16 vitalu
Jumla ya vitalu vilivyopinduliwa: 7 + 10 + 16 = <<7+10+16=33>>33 vitalu
