This problem follows on from Arrow Arithmetic 2 .

Things start to get interesting when we try to multiply twizzles together. In the following animation, the grey twizzle is the product of the blue and green twizzles. You can try several multiplications by unlocking the green and blue twizzles and changing their values.

How can you construct the grey twizzle by transforming the green and blue twizzles?

If you switch the unit arrow and the number arrow in a twizzle, how does its value change?

In the following animation, the grey twizzle is the blue twizzle divided by the green twizzle. How could you construct a quotient twizzle like this grey one with the right value?
