Scientific notation questions appear regularly on the DAT Math (Quantitative Reasoning) section and are a common source of avoidable errors.
In this short video, Prof. Blois demonstrates how to correctly add numbers written in scientific notation, with emphasis on aligning exponents first ā exactly how the DAT expects these problems to be handled.
Key points covered:
- Matching exponents before addition
- Avoiding setup mistakes that cost easy points
- High-frequency DAT math concept
This type of problem is practiced extensively in the Math Destroyer, which contains DAT-style questions with full, step-by-step solutions.
