Question

Daca a=200, b=500, c cu 400 mai mare decat a; d cu 100 mai mic decat b afla: a+b, b+d, c-a, b-d, c+d-a, c+d-(a+b)

Answer 1

a=200
b=500
c=a+400
d=b-100
r-e:
c=200+400=600
d=500-100=400
a+b=200+500=700
b+d=500+400=900
c-a=600-200=400
b-d=500-400=100
c+d-a=600+400-200=800
c+d- (a+b)=600+400- (200+500)=1000-700=300
