Question

как сделать номер 177

Answer 1

1) (74+x)+38=74+x+38=x+74+38=x+112

2) 238+(a+416)=238+a+416=a+238+416=a+654

3) y+342+546=y+870

4) 2.753+m+4.199=m+2.753+4.199=m+6.952

5) (b+457)+(143+872)=b+457+143+872=b+1.472

6)  (2.235+с)+(4.671+1.765)=2.235+с+4.671+1.765=с+4.671+4.000=с+8.671

7) (1.696+3.593)+(p+1.304)=1.696+3.593+p+1.304=3.593+p+3.000=p+6.593

8) (5.432+8.951)+(4.568+а+1.049)=5.432+8.951+4.568+а+1.049=(5.432+4.568)+а+

+8.951+1.049=10.000+а+(8.951+1.049)=10.000+а+10.000
