A and B agreed to meet at a restaurant for a meal. Due to the restaurant being very busy, A arrived first and took a waiting number and waited for B. After a while, B also arrived but did not see A, so he took another waiting number. While waiting, B saw A, and they took out their waiting numbers and discovered that the digits of these two numbers are reversed two-digit numbers, and the sum of the digits of both numbers (for example, the sum of the digits of 23 is $2+3=5$) is 8, and B's number is 18 greater than A's. What is A's number?
