Answer 1

Răspuns:

a.36 526- 28 635=7 891

Proba : 7 891 +28 635=36 526

36 526- 7 891= 28635

61.382-46859= 14 523

P; 14.523 + 46.859=61.382

61.382-14.523=46.829

b. 280. 026 -89.275=190.751

P;190.751+89.275=280.026

280.026 - 89.275 = 190.751

784.005 - 708.906 =75.099

P: 75.099+708.906= 784.005

784.005 - 75.099 = 708.906

c . 101 384-75.609=25. 775

P :25.775+75.609=101.384

101.384-25.775

340.510- 265.520= 74.990

P: 265.520+ 74.990= 340.510

340.510 - 74.990= 265.520
