X+y=2,1+3,5 = 5,60
x-y=2,1-3,5= - 1,40
x*y =2,1*3,5 = 7,35
x/y = 2,1/3,5 = 21/35=3/5 = 0,60
x+y=6,18+2,24 = 8,42
x-y=6,18-2,24=3,94
x*y=6,18*2,24=13,8432 ≈ 13,84
x/y = 6,18/2,24 = 618/224=309/112 ≈ 2,76
x+y=1,12*10^(-2)+6,08*10^(-2)=7,2*10^(-2) = 0,072 ≈ 0,07
x-y=1,12*10^(-2)-6,08*10^(-2)=-4,96*10^(-2) = -0,0496 ≈ -0,05
x*y=1,12*10^(-2)*6,08*10^(-2) ≈ 6,81*10^(-4)
x/y=1,12*10^(-2)/6,08*10^(-2) ≈ 0,18
