I want to use the backwards method, first consider seeing: learn + use ()=mathematics, first of all, the 'number' is 1, because the addition of two numbers can only go up to 1.

The main consideration is 'learning' and 'use'. The addition of the four numbers can be carried up to 3, so it can be assumed that 'learning' is x: x+4x+2=10+x, and the solution is x=2

That is, learning is 2, and using is 8; Then start thinking about the ten: learn + use = 10, then you still need to enter 12 to meet the requirements so 12 2 = 6, good is 6.

This brings me to the question abcd 4=dcba.

It's better to write this equation vertically, and then consider that the addition has a carry, so it is rewritten as:

Learn mathematics. with mathematics.

Learn math well. Use good math.

Carry ab c d

Mathematics for use.

The result is from right to left, it can be obtained: d use = learn * 4, c is = number * 4 + d, b learn = learn + use + good * 2 + c, a learn = learn + use + b, number = a

with'It's definitely even, and it won't be'0', so'Learn'It won't be'5'。

Obtained from a learning = learning + using + b: using +b = a 0;And because all the numbers represented by Chinese characters and letters are only selected from 0 9, a can only be equal to 1, that is, "number" = a = 1.

From b learning = learning + use + good * 2 + c obtained: good * 2 + c = 10 * b - use = 10 * b - (10-b) ......With +b = 10

11*b-10

Since both good and c are only selected in 0 9, 0 "good*2+c<30, that is, 0<11*b-10<30, plus b is an integer, so b=2.

Therefore with =8.

From a learning = learning + using + b we can see that learning <5, therefore, learning can only be 2.

So d = 0, is = 4, c = 0.

Then from b learn = learn + use + good * 2 + c get: 22 = 2 + 8 + good * 2 + 0, so good = 6.

To sum up, this equation is:

Carry 12

Let number = a learn = b good = c

Then there is aba bab cbbc

Obviously, a b 10, c can only be equal to 1

Because a b corresponds to c in the single digit

A and B correspond to B in the ten digits

So b c 1

So b 2a b unit is 1, and there can only be a 9

, soNumber = 9

Learn = 2 good = 1

Learn math well with math.

Use good math. Mathematics for use.

1) "Learn" can only be 2, "use" is 8, if it is 1, "use" can only be 4, and it is impossible to carry.

2) By "number" = 1, "for" = 4

3) "use" + "good" + "good" should be 20 (if it is 10, the carry is not enough) "good" = 6i.e. 212

Good = 1, Learn = 2, Number = 9

Three digits plus three digits equals four digits, so four digits thousands of digits are 1, so good = 1;Number + learning = 1 or 11, obviously not equal to 1, then 11. Command number = x, learn = 11-x, mathematical number + learn mathematics = (100x + 10 (11-x) + x) + (100 (11-x) + 10x + (11-x)) = 1221So learn = 2, number = 9

Solution: Setup = a learning = b good = c

Then there is aba bab cbbc

Obviously, a b 10, c can only be equal to 1

Because a b corresponds to c in the single digit

A and B correspond to B in the ten digits

So b c 1

So b 2a b unit is 1, and there can only be a 9

So number = 9 learning = 2 good = 1

Not many people understand how the title is written.

The title should be:

Learn Mathematics + Use Mathematics + Learn Mathematics well + Use Mathematics well Mathematics for Analysis: 1. The result is a five-digit number, so the number = 1

2. Use = 4 to learn to add, and use not to be zero is an even number, and the result of the thousand digits is learning, the four numbers of the hundred digits are added up to two digits, so with = 8, then learn = 2 or 7

3. When learning = 2, use = 8, for = 4, number = 1, good = 6, when established when learning = 7, use = 8, number = 1, for = 6, good = 6, and for the same, so give up to understand, please adopt as a satisfactory answer, do not understand, please ask!
