If 5 plus 3 plus 2 equals 151012 and 9 plus 2 plus 4 equals 183662 and 8 plus 6 plus 3 equals 482466 and 5 plus 4 plus 5 equals 202504 then 7 plus 2 plus 5 equals?

143542

make the variables X plus Y plus Z

the solution is X*Y,X*Z, then (X+Z)*Y flipped

7*2=14

7*5=35

(7+5)*2=24 flipped =42

143542

5*3=15

5*2=10

(5+2)*3=21...flipped =12
