Video Summary

A student correctly added two two-digit numbers, resulting in 137, and needs to add two specific four-digit numbers, ADCB and CBAD. By breaking the numbers into their components and applying arithmetic operations, the expression simplifies to 101 times the sum of the numbers formed (AB + CD). Given that AB + CB equals 137, the final computation yields 101 times 137, resulting in an answer of 13,837.
