### Why do this problem?

This problem practises working systematically on addition and subtraction. This is a code, not algebra, and learners will need to try things out as well as working them out, so using trial and improvement will be essential.

### Key questions

Have you remembered that this is a code?
Have you thought of looking at the two number plates beginning with V?
Have you thought of writing out the alphabet and thinking of a way to turn the letters into numbers?
Can you think of a variation on the most obvious way of turning letters into numbers?

### Possible extension

Learners who found this problem easy could try Ishango Bone.

### Possible support

Suggest starting by writing out the numbers on the number-plates and adding up each one. Then write out the alphabet and think of a way of varying A = $1$, B = $2$ etc.
