Each kanji represents a number that makes the equation hold.

Happy Math + Happy Heart = Happy Math Open = A, Heart = B, Mathematics = C, Learning = D

abcd+aabb=cdab

It is superimposed from everyone to a thousand at once.

d+b=bc+b=a possible carry.

So d=0

If c+b does not carry b+a=d=0, it must be carryed.

If c+b does not carry b+a+1=d=0, it must be carryed.

a+a+1=c c cannot be zero and less than 10

a is 1 2 3 4

c is 3 5 7 9

If a=1 then c=3 c+b=11 b=8 verify that 1830+1188=3018 is correct.

If a=2, then c=5 c+b=12 b=7 verifies that 2750+2277=5027 is correct.

If a=3, then c=7, c+b=13, b=6, verify that 3670+3366=7036 is correct.

If a=4 then c=9 c+b=14 b=5 verify that 4590+4455=9045 is correct.

So Happy Math 1830 2750 3670 4590

Be happy + 1188 + 2277 + 3366 + 4455

Math Happy 3018 5027 7036 9045

Fun, joy + really fun = really happy.

abc+dea=deab

c+a=b may be carried.

b+e(+1)=a possible carry (parentheses indicate that there may be a preceding carry 1).

a+d(+1)=de with a certain carry, then d=1, e=0.

Then a If a=9, then there is no carrying, so |b+e=a，b=9，c+a=b，c=0。then b=a, c=e are wrong.

b+e+1=a，b=8，c+a=1b，c=9。then c=a is wrong.

If a=8, then there is a carry, so b+e+1=a, b=7, c+a=1b, c=9. But b+e+1 is not carryed, wrong.

So. Le Ah Le ABC

It's really fun + dea

— There is no answer, unless a=b=9, c=e=0, d=1. or a=c=9, b=8, d=1, e=0

What a joy deab

i.e., 989 990

1 There is more than one answer to the happy math.

1830 + 1188 = 3018 2750 + 2277 = 5027 3670 + 3366 = 7036 4590 + 4455 = 9045 can be.

In the following equation, different Chinese characters represent different numbers, guess how many each number represents = 1 good = ( ) do = ( ) do = ( ) things = (

Hello, calculated good = 9, things = 8, do = 0

(1) According to the addition of the two compound "pawns" on the single position, and.

The single digit is still "baipa", and "dupa" = 0;

"rook" = 1, the "pawn" on the ten is 1 larger than the "horse"; zhi

According to the analysis of the question stem, it can be obtained: I-love = I love;

So I = 4, love = 2;

Substituting me = 4 and love = 2 into the first equation and the second equation yield:

Mathematics + learning = 8;

Learn - number = 2, then learn = number + 2, substitute it into number + learn = 8, you can get number + number + 2 = 8, then number = 3;

So learn = 3 + 2 = 5;

Answer: The four-digit number represented by "I love math" is 4235, so the answer is: 4235

According to the analysis of the question stem, it can be obtained:

Answer: Ao = 5, Yun = 0, Hui = 4, Office = 1

Since the thousand digits of the subtracted number are "wishes", and the thousands of the subtraction and difference are 0, so "wishes" = 1, then the subtracted number is at least 10 times that of "good wishes", so "good, good" is at least 9 times that of "good wishes", and it can be obtained, "good" = 9;

From the single digit, "ah" -9 = 9, only ten digits go up and down 1, that is, 18-9 = 9, so "ah" = 8;

On the tenth, 9-1-8="you", so, "you"=0 vertically:
