IIT JAM virtual calculator is an essential tool for performing complex numerical calculations during the exam. Basic mode is used for simple arithmetic operations (addition, subtraction, multiplication, division). Whereas, the advanced mode includes scientific functions for trigonometry, logarithms, exponents, roots, and other mathematical computations.
IIT JAM virtual calculator consists of two modes: Basic and Advanced mode. Since physical calculators are not allowed in the IIT JAM exam, it is essential for candidates to familiarise themselves with the virtual calculator and its functions beforehand. Mastery of the virtual calculator can save time during the exam and improve accuracy in calculations.
IIT JAM virtual calculator was introduced in 2016 and helps students solve problems effectively in less time while they are taking the IIT JAM exam.
