[Tutor] Problem

[shahan khan]

I changed the code a bit and this is the result:
for a in range(1,11):
for b in range(1,6):
for c in range(1,6):
mc=(6*a)+(9*b)+(20*c)
if mc==50:
print 'For 50 McNuggets:''a=',a,'b=',b,'c=',c
if mc==51:
print 'Fpr 51 McNuggets:''a=',a,'b=',b,'c=',c
if mc==52:
print 'For 52 McNuggets:''a=',a,'b=',b,'c=',c
if mc==53:
print 'For 53 McNuggets:''a=',a,'b=',b,'c=',c
if mc==54:
print 'For 54 McNuggets:''a=',a,'b=',b,'c=',c
if mc==55:
print 'For 55 McNuggets:''a=',a,'b=',b,'c=',c
Result:
For 55 McNuggets:a= 1 b= 1 c= 2
For 53 McNuggets:a= 1 b= 3 c= 1
For 50 McNuggets:a= 2 b= 2 c= 1
For 53 McNuggets:a= 4 b= 1 c= 1

Two questions:
1) why is it printing backwards? 2) why is it skipping 51,52 and 54?
