\(A=131\cdot\left(35-27\right)-35\cdot31+131\cdot207\\ A=131\cdot35+131\cdot27-35\cdot31+131\cdot207\\ A=35\cdot\left(131-31\right)+131\cdot\left(27+207\right)\\ A=35\cdot100+131\cdot234\\ A=3500+30654=34154\)
A=131.(35−27)−35.31+131.207
A=131.35+131.27−35.31+131.207
A=35.(131−31)+131.(27+207)
A=35.100+131.234
A=3500+30654
A=34154
