Question 12
In the column addition AB+BA=CC, each letter represents a digit and AB, BA, CC are two-digit numbers. Find at least five different assignments of values to A, B and C that make the addition true. Write each assignment and check its sum.
Use the usual letter-digit convention: different letters have different digits within an assignment. A, B and C cannot be zero because each begins a two-digit number. “Five values” is understood as five complete assignments, as in the source key.
