However... On the PMP Exam you have just 1.2 minutes to answer each question. So don't make this harder on yourself than necessary. During the exam you can use an on-screen calculator (windows based) and you don't have to calculate anything by hand. In fact, I recommend that you use the on-screen calculator even if you have to calculate 2*5=? because the exam is a stressful time and you could easily make a mistake and then 2 times 5 is suddenly 12.
