A typical AA battery delivers a nearly constant voltage of 1.5 V and stores about 104 J of energy. From the time it takes you to use up the batteries in your calculator estimate the resistance of your calculator. (If you don't have a calculator of this type, make a plausible estimate of how long it might take to use up the batteries. Give some reason for your estimate.)
