265+2=267

267÷3=89

89- 1=88

89+88= 177

——————————————— The following is the explanation.

134+131= 265 is a number of one (A+D)+ two (B+C);

Add 2, and it becomes the number of three (A+D) 267;

Divided by 3 is the number of (A+D) 89;

(B+C) is less than (A+D)+0, and 65438 is 88;

The total is 89+88= 177. I wonder if this explanation is an elementary school arithmetic expression.
