So the last digit A+C= 10+B is A+C= 1 1.
The middle bit B+B+ 1=C, so C=3,
So A= 1 1-3=8.
The answer is a = 8；; b = 1； c = 3；
The knowledge points of addition and carry in mathematics are mainly used here. In the decimal algorithm, if every digit is full ten, add1to the decimal digit; When there are ten people to ten, add one to a hundred. This problem is actually a three-digit addition operation, that is, 813+318 =11.
In basic arithmetic, carry is a form of operation. In addition, when the number on each digit is equal to the radix, it is part of the standard algorithm to move forward by one digit. It starts from the rightmost number and then passes it to the left. ?
Mathematics (Mathematics or maths, whose English comes from the Greek "Má th ē ma"; Often abbreviated as "mathematics"), it is a discipline that studies concepts such as quantity, structure, change, space and information, and belongs to a formal science from a certain point of view. Mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.
In the development of human history and social life, mathematics also plays an irreplaceable role, and it is also an indispensable basic tool for studying and studying modern science and technology.
