The following is a detailed explanation for you:

Let me, love, mom and dad be x, y, z and w respectively.

Then I love my parents x4= My parents love me = (1000x+100y+10z+w) x4 =1000w+100z+x.

We can also note that if 2500X4= 10000, then X= 1 or 2, Y=0, 1, 2, 3, 4,

Ideas y and z are both numbers multiplied by integer ten, so the mantissa of 996W must be the same as the previous fixed number.

When X= 1, 3999+390Y=60Z+996W is brought in, but the mantissa is 9 when no number is multiplied by 6, so x is not equal to 1.

When x=2, we get 7998+390Y=60Z+996W, and it is easy to miss W=3, so W=8.

Now we can get 3+39Y=6Z, and it is easy to get Y= 1 and Z=7.

Thank you. If you don't understand, you can use your own pen to check.
