Explicație pas cu pas:

a) 13.5+2.7-6.8 = 16.2 - 6.8 = 9.4

b) 5.23-2.23+14.9 = 3 + 14.9 = 17.9

c) 81.43+18.57-23.64 = 100 - 23.64 = 76.36

d) 456.258-208.208+54.65 = 248.05 + 54.65 = 302.7

e) 18.3458-6.0059+10.203 = 12.3399 + 10.203 = 22.5429

f) 79-23.503-4.8563+1.8 = 55.497 - 4.8563 + 1.8 = 50.6407 + 1.8 = 52.4407
