Yep; I got it in the deluxe starter pack which was £20 at the time (on offer)- you get a calculator, the shopping guide, the eating out guide, a tape measure, a weight watchers pen with green highlighter (to highlight filling and healthy foods), a track book (a 12 week journal to write down what you eat everyday, track weight loss, measurements and record exercise) and some money off vouchers which I haven't used. I got this because it was cheaper than buying the calculator and books separately.
I think the calculator is £10.95

and it works out how many propoints you should be on when you enter your details and you can use this to track too- example, under propoints it asks to calculate or use, if you press use then say 7 for what you had for breakfast, it will deduct 7 from your daily amount. If you use more, it takes out of your weeklies. Can't add activity points though

You can also use the points you worked out too say if it came out at 10 after propointing, it asks if you want to use them.
I love mine

And I hope that wasn't too confusing?
Edit:
Here's a link to the WW electronics, the calculator is at the top-
