Does anyone know the solution for these puzzles? Explanation with Rechweg would be nice

IRIS

Another idea would be

4 + 4 - (1) = 7

7 + 7 - (4 + 1) = 9

8 + 8 - (7 + 4 + 1) = 4

That would not include the 3 of the first equation.

10

My logic:

1 -> 4 -> 7 -> 8 is the differential sequence 3 -> 2 -> 1 (ie always -1)

3 -> 7 -> 9 -> 10 has the division sequence 4 -> 2 -> 1 (ie always by 2)

Rufus

8 + 8 = 10

On the left you add from line to line 3, 2, 1

On the right you add from line to line 4, 2, 1 (always half)

Henrietta

8 + 8 = 16

Only because other mistakes do not have to do which ones.
