You know that root 2 is an irrational number, and irrational numbers are infinite non-recurring decimals, so we can not write all the decimals of root 2, so small The root 2-1 is used to represent the decimal part of the root 2. Do you agree with Xiao Ming's representation? In fact, Xiao Ming's representation is reasonable, because the integer part of root 2 is 1. Subtract this number from its integer part, and the difference is the decimal part. Ask: Given 10+ root 3=x+y, where x is an integer and 0< y <1, find the opposite number of x-y.
