Question

calculează a+c-(b-d),stiind că: a=c+400.002 ;b=d+c;c=d-600;d=749.603-709.001

Answer 1

d=40.602
c=40.602-600
c=40.002
b=40.602+40.002
b=80.604
a=40.002+400.002
a=440.004

a+c-(b-d)=440.004+40.002-(80.604-40.602)=480.006-40.002=440.004

Answer 2

d= 749.603-709.001
d= 40602

c= 40602-600
c= 40002

b= 40602+40002
b= 80604

a= 40002+400002
a= 440004

440002+40002-(80604-40602)
=480004-40002
=440002
