Apraxia Algera is a rare medical condition that affects a person's ability to perform mathematical calculations. The term is derived from two separate words, "apraxia" and "algera." The word apraxia refers to the inability to carry out familiar and purposeful movements, while the word algera refers to mathematical operations involving letters and symbols. The correct spelling of this condition is /əˈpræksiə ˈældʒərə/. People with Apraxia Algera may have difficulty with basic arithmetic, such as addition and subtraction, and may experience frustration and anxiety when attempting to solve mathematical problems.
An hysterical condition in which speaking, reading, writing, or consecutive thinking is impossible owing to the severe headache it causes.
