So I * 1000 is a multiple of my love of mathematics.

Learn * Learn last or Learn, learning can be 0, 1, 5, 6.

But I * 1000 is a multiple of my love of mathematics, and my study can only be 0 or 5.

If the study is 0, I love math. The last two digits are 0, and math =0. No, give it up.

If you learn 5, number * number +2 is the last digit or number, the number can only be 2.

25* Love 25= I love 25

5* love +6 finally is love, and love is 1 or 6.

25* 125=3 125

25*625= 15625

So only 25* 125=3 125.
