What is the sum of the mantissa of the addend less than a zero and the correct answer less than 36 in solving math problems in the second grade of primary schools in Shanghai?
40
If one constant addend is a, the other addend should be B.
If you add a zero less, then b becomes110b.
So, you can list
(A+B)-(A+ 1/ 10B)=36
B=40 solution
