Rita   Thank you for your question and welcome to ADHDCentral.com.   ADHD does not impact math abilities. ADHD impacts the ability to pay attention, which may cause problems with not hearing the information taught in school or being distracted when completing homework. If you are having a difficult time with your daughter in math, you may want to consider asking the school to evaluate your daughter for  a math learning disability.   For more information:   ADHD and Learning Disabilities   Suggestions for Winning the Homework Wars   When Parents Feel Their Child Needs Special Accommodations   I hope this helps   Eileen
