Katrielle and the Millionaires' Conspiracy walkthrough
Puzzle Location: Parliament Square Garden (Douglas Dert)
There are spaces for number panels in this two-by-two stone grid.
Place the panels so that adding or multiplaying two numbers horizontally or vertically results in the number shown between the two panels.
Slide the panels to move them and place them in the grid.
First try to exclude the panels that don't equal the numbers in the middle, regardless of weather they are added or mutiplied.
There are two addition sums and two multiplication sums.
The top numbers should be added together, while the bottom numbers should be multiplied.
The number that goes at the bottom-right is '13'.
Use this information to figure out what goes in the other empty slots.
The answer is as follows.
top-left＝14
top-right＝22
bottom-left＝4
bottom-right＝13
