Special Mathematics in Grade Four
Solution: Let the original two addends be X and Y,

Both numbers are two digits,

When the number 3 of x is considered as 8 and the decimal number remains unchanged, for example, it is 73. 3 when 8, 73 when 78. 78 adds up to 5, and the result is X. If it is wrong, the result is (x+3). When 9 in the decimal number of y is regarded as 5, it is 49 and 45, so 49 should be added.

The correct answer is x+y.

He misread (x+3)+(y-4)=x+y- 1=225 and came out.

x+y=225+ 1=226

A: The correct answer 1 is 226.
