Video Summary

Ava wrote a 3-digit number, ABC, on the whiteboard. Brandon added a fourth digit, D, stating the number increased by 2024. Representing the final number as ABCD, it follows that ABCD equals ABC times 10 plus D. The difference, ABCD minus ABC, equals 2024, leading to the equation 9 * ABC + D = 2024. Solving 2024 divided by 9 yields ABC = 224 and D = 8, so Ava's number was 224 and Brandon added 8, creating 2248. This addition of 8 correctly increased the number by 2024. Brandon wrote the digit 8.
