The video tutorial from M Math and Science explains how to subtract decimals by aligning the decimal points and borrowing when necessary. It provides two examples: subtracting 410 from 32 and subtracting 72 hundredths from 1 and 4 tenths. The tutorial emphasizes the importance of lining up decimals and borrowing correctly. It concludes with a motivational message about kindness.
