It has a solar battery. It has to be in the light, either sun light or artificial light to operate. HOWEVER, if the battery is shot, it must be replaced. Take your calculator to any radio shack store and ask them to test the battery for you. If it is no good, they will be able to replace it for a fee.

1. To convert a number to scientific equation, use [2nd][Sci]
Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.
2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65
1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19
Hope it helps
