A simple (Sada / ordinary calculator) will do the job. Scientific calculators also allowed. No significance of sd function unless you know how to use it very well. Scientific calculators allow use of brackets and can store some memory as M in M+ and MR etc. and that is why slightly better than ordinary calculator. Otherwise ordinary calculator is also more than sufficient.

Mobile phones are not allowed to be used as calculators.
