I think that the picture of 2 galleys are not the same that the sum of 1 galley plus 1 galley, is clearly a multiplication.




1. X+X+X=75

2. X-Y+Z=21

3. Y+Z^2=7



1. 3X=75 

X=25

1. & 2. 25-Y+Z=21 

Y=Z+4


2. & 3.

Z+4 + Z^2 =7

Z^2 + Z - 3 = 0



Quadratic equation with 2 solutions, where:


Z= -1+- SQR( 1^2 - (4x1x(-3))) / (2x1)


Z1= 1.305  then  Y1 = 5.305

Z2 = -2.305 then Y2 = 1.695


So:

Z + YxZ = is

a) 25 + 5.305 x 1.305 = 31.923

b) 25 - 2.305 x 1.695 = 21.093

the answer = 126


25 + 25 +25 = 75

25 - 5 + 1 = 21

1 + 5 * 25 = ?  is like 1 + (5*25) =

1+ 125 = 126

75/3 = 25= catapult

25 - 5 + 1= 21 5=arrows 1 = ship

5 + ( 1+1) = 7

(1 + 5) = 6 x 25 = 150

25 + 25 + 25 = 75

25 - 5 + 1 = 21

5 + 2 = 7

1 + (5 x 25) = 126


priorité pour les multiplications. ;)
