Question

Oblicz: a) 3,49+125,8 25,3+0,089 135,7+97,94 b) 147,3-28,1 206,2-141,48 83,06-39,503 c) 57,83+0,874-9,17 9,04-7,155+11, 84 100-4,87-28,906

Answer 1

a) 3,49+125,8 = 129,29

  25,3+0,089 = 25,389

135,7+97,94 = 233,64

b) 147,3-28,1  = 119,2

206,2-141,48 = 64,72

83,06-39,503= 43,557

c) 57,83+0,874-9,17 = 58,704 - 9,17 = 49,534

  9,04-7,155+11,  84= 1,885 + 11,84 = 13,725

100-4,87-28,906 = 95,13 - 28,906 = 66,224
