For example take the four times table

and add a Three card to each pile.

Calculating the resulting numbers give this sequence of cards

We have taken a hand

*in the four times table and*

added three to the hand .

This is recorded as 4

*+ 3, with the result depending on the declared value for*

**x***.*

**x**As it is based on the four times table we note that each number in the sequence is four more than the previous number.

This leads to two new puzzles.

- Given a sequence of numbers find out if it is a disguised times table and find the hand that would play the sequence.
- From a maths record of a disguised times table find the declared value of
.*x*
