You better read this guide after you complete most of the puzzles, it's meaningless for anyone to copy the answers to clear all the levels without thinking. This guide is just to provide ideas about how to deal with these puzzles.

你最好在通关后或者完成大部分关卡后再来看这篇指南，不经过思考就直接抄答案没有意义。这个指南仅仅是提供一个过关思路。

5-6 A/B now 13/40. More difficult to read.

ab0=1ab
ab1=1abab
/1=/ab
(once)1=0bbabababbab/ag/abbabab/ab/ag/ab
baabba=abbaba
aab=(end)ba
bag/abbabab/a=abag/abbabab/aba
bab/ag/abbabab/ab/ag/=(end)bag/abbabab/abab/ag/abbabab/a
bab/ag/abbabab/ababa=b/ag/abbabab/aba
bb/ag/abbabab/ab/ag/abbabab/aba=,0
0ba=1
1ba=ba0
ba=1

This is a direct promotion of the 15-line version. I use 'ba' instead of 'a' and 'ab' instead of '+', in which case 'a=+' can be hidden in other lines. The hard part lies in deleting the last 'b' created by line 1-3. This is solved by running line 7 twice and then line 6 in the beginning(afterward line 6 and 7 appear in turn). Line 8 is always a disaster. In this program line 8 also has to make sure that the condition of line 7 is not satisfied when it is the turn for line 9 (this cost me many hours!).

5-6 15 lines is possible, just looks like not something humans can read.

a0=0aa
a1=0aaa
(once)/1=a,0g+a,0,0ga,0a
(once)1=0a
00a=0a
d=(end)a
ag+a,0=dg+a,0a
a,0g+a,0,0g=(end)g+a,0,0g+a,0
a+=+a
a,0g+a,0a=,0g+a,0
,0g+a,0,0g+a,0a=,0
a=+
0+=1
1+=+0
+=1

Comments. 'a' in 6-1, line 1-5 transform two numbers to '0aa'. '+' means add 1 to a number, line 13-15 transform '0++' to number. Line 6,7 copies divisor to end separated by 'g+a,0'. Line 9 makes sure '+' is at start. There are 3 numbers, dividend ',0g+a,0' divisor ',0g+a,0' divisor. If dividend > 0, line 10 substracts the first two numbers and goto line 8, otherwise substract the last two and goto line 11. Line 11 deletes the separate symbols. Line 12 transforms remainder from '0aa' to '0++'. Line 8 is hardest(maybe hardest in this game), means add 1 to the quotient, delete 1 separate symbol in the middle, and add 1 separate symbol at end. To do this, '+' is hidden in the separate symbol and line 8 deletes the 'g' so '+' appears.

6-3 another 13-line solution:
#there are at most five c's in between a and b
ab=bb
ba=bb
acb=bcb
bca=bcb
accb=bccb
bcca=bccb
acccb=bcccb
bccca=bcccb
bcccca=bccccb
accccb=bccccb
bccccca=bcccccb
acccccb=bcccccb

a=c

This community has given me the impetus to think a lot about problems.I wouid like to leave my solutions here as token of my gratitude.

Thank you very much for this guide; it helped me finish the game after the game stopped being fun and just became overwhelming
