The QAMA Calculator is a calculator that requires users to provide a reasonable estimate of the answer before the precise answer is delivered.[1][2] QAMA stands for Quick Approximate Mental Arithmetic.
Invented by Ilan Samson, it aims to get users to think first by estimating before they get the correct answer.[3] Estimation is seen by many as an essential part of mathematics, and some believe that the presence and popularity of calculators could inhibit the use of estimation skills.[4][5]
A physical version of the calculator was released for sale in 2014, with apps for smartphones and tablets developed in 2016.
