    He asserted that the square root of a negative number does not exist. [12] Arithmetic operations utilized in his works like Gaṇita-sāra-saṅgraha(Ganita Sara Sangraha) uses decimal place-value system and include the use of zero. However, he erroneously states that a number divided by zero remains unchanged. [13]

[2] For both, a 20-inch (500 mm) box fan makes the last side of the cube and is duct taped to the filters, sealing the system so that air is drawn through the filters and out of the box. [21] [16]
