To start: Hover your cursor over the large red box. This box contains icons that represent the cost of various items relating to West Bank settlements. A text will pop up, explaining what each icon represents, as you hover over it. To choose an icon, click on it and
drag it to the small red box beneath it.
Once you have chosen a settlement icon, hover your cursor over the large green 'Products/Services' box. Select your icon and
drag it to the small green box beneath.
Now, in front of you, you have an equation demonstrating how much Israeli taxpayers could do with the money - their money - that their government spends on the settlements.
On the bottom of the page, in the comments section, you will find some clarifying information about many of the items.
