Science from primary school multiplied by 4 equals that subjects love small subjects. From, small, love, science, learning, how many are equal?
1, love of mathematics from childhood multiplied by 4 is equal to learning mathematics from childhood and loving learning.

(1) First of all, five digits multiplied by four equals five digits, so these five digits must be less than 25000, then "cong" must be 1 or 2, and the mantissa of digits obtained by multiplying "xue" by four must be even, so "cong" can only be 2, so "xue" = 2 * 4 = 8;

② If "Xiao" *4 does not carry, then "Xiao" must be 1 or 2 and "Xue" *4=32, then the mantissa of "number" *4+3 is "Xiao", which means that "Xiao" is odd, so it is1; Then "number" is only 7 ("number" is not 2 because "small" * 4+b >;; 4);

(3) Because "small" *4+b= "number" (b is the decimal number of "love" *4), then b is 3, so there is the formula a*4+3=3a (let "love" be a and 3a be a two-digit number), we can see that a=9, that is, "love" is 9;

To sum up: I loved mathematics since I was a child =2 1978.
