5+3+2 = 151022
9+2+4 = 183652
8+6+3 = 482466
5+4+5 = 202341
Then...
7+2+5 = ??????
​

Answer 1

5+3+2=151022......in this.15=5*3,10=5*2,22=15+10-3

9+2+4=183652......in this.18=9*2,36=9*4,52=18+36-2

8+6+3=482466......in this.48=8*6,24=8*3,66=48+26-6

5+4+5=202541......in this.20=5*4,25=5*5,41=20+25-4

so....

7+2+5=143547........in this.14=7*2,35=7*5,47=14+35-2
