Because I love math ×4, I still have 4 digits, so I can only get 1 or 2.

And because the unit of learning x 4 is me, I can only be an even number. Therefore, I =2, learning =3 or 8(3×4= 12, 8×4=32, so that the unit satisfies 2).

If I am 2, then one thousandth of my study must not be less than I× 4, so my study can only be 8 or 9. So, learning =8.

Learning is equal to 8, that is, I× 4, so I love that the hundred digits× 4 of mathematics do not carry. In other words, love math ×4= number loves me. It's still three digits, so love = 1 or 2.

because

If the decimal digits and unit digits of mathematics× 4 love me, then love =4× number +3, then love must be the cardinal number. So love = 1

Similarly, the inferred number =7.

Even if I =2, love = 1, number =7, learning =8.
