add a line to the first '+' and it becomes a '4' so... 545 + 5 = 550

4 -> (4^2) +1 = 16+1 = 17 -> 1+7=8
5 -> (5^2) +1 = 25+1 = 26 -> 2+6=8
8 -> (8^2) +1 = 64+1 = 65 -> 6+5=11
Answer: 65 +11= 76

i think 4 = 17 5 = 17 +9 6=17+9+9 8= 17 +9+9+9+9=53 it's for y Depending of the point of view the answer could be right or not, but I can't guess the way that you think

Multiply 12*12=144 Sum of the digits of its product 1+4+4=9 Therefore 12*12=9 In the same way Multiply 23*23=529 Sum of the digits of its product 5+2+9=16 asnd now Multiply 34*34=1156 Sum of the digits of its product 1+1+5+6=13 Therefore 34*34=13 :sleep: was a hard one :king:
