Answer 1

87658 + 68763 + 18764 = 175185

1) 87658 + 68763 = 156421

2) 156421 + 18764 = 175185

986409 + 5876 + 5432 = 997717

1) 986409 + 5876 = 992285

2) 992285 + 5432 = 997717

6786 + 46896 + 41089 = 94771

1) 6786 + 46896 = 53682

2) 53682 + 41089 = 94771

60999 +45398 + 10342 = 116739

1) 60999 + 45398 = 106397

2) 106397 + 10342 = 116739

247 * 27 = 6669

239 * 454 = 108506

460598 / 782 = 589

144560 / 695 = 208
