In my header file, i am trying to send inva11,inva12,inva21,inva22 to the method multiplication and from multiplication i am trying to send x, and y to method setAB, does anyone have any suggestion on how I can do this.

```cpp
int main() {
return 0;
}
```

[left ginkgo]

you can make your inverse function modify the object members abcd instead

the code using this class should do get some return value from Multiplication (poor name btw needs to be more descriptive), then pass that along to SetAB

[jovial prairie]

How exactly do i do that?

[left ginkgo]

You can return a struct or a pair of doubles

I'm a beginner can you, maybe show me?
