HeadMath for Division

This audio file recites subtraction equations while it plays music that tunes your brain to the alpha wave frequency. Scientific studies have demonstrated that cognition is enhanced when the brain is producing alpha waves.

There are sixteen file options. Please select an option on the right with those attributes that work best for you. The attributes are defined below:

• Covers 1-20 -- The file shows combinations of equations for numbers between 1 and 20
• Long Playing -- The file has a running time of 1-2 hours.
• Test Pause -- Each recited equation has a 2-second pause before giving the answer. This allows users to try to remember the answer before it is given.
• No Remainders -- Only equations that yield whole number answers are included.
• Decimal Remainders -- Reminders are represented as decimals.
• Fraction Remainders -- Remainders are represented as fractions.
• Integer Remainders -- Remainders are represented as integers.
