This year is the 90th anniversary of the founding of the Communist Party of China. Xiao Ming learned from the information that the first party congress of the Communist Party of China was held in Shanghai at 20:00 on July 23, 1921. Xiao Ming saw that this group of numbers composed of dates is very characteristic, so he designed an addition operation program on the computer. This program only needs to input 9 numbers of 192172320 in sequence, and the computer will immediately display 90. Please add a few numbers between these numbers. A "+" sign makes the sum 90, what is the formula for this addition operation.
