hello,
I'm a french teacher and I apprécitate most of h5p tools.
At the present time, I'm using Arithmetic Quiz but I'm not fully satisfied. In fact I miss the possibility of choosing which addition/substractio/multiplication/divide table : for instance I'd would like to choose only additions with 9 : 2 + 9 , 23 + 9, 42 + 9 etc.
