Best entry level DSLR ..

Not too badly, although I'm not great with all the calculations such as

2.08 x 10 to the power of -19
divided by
5.0 x 10 to the power of -15 I have no idea how to do that on a calculator !

But explaining why a balloons pressure increases in heat was easy :3

well you should know what X^-19/X^-15 is like -19--15 = -4
and on a calc you would know what 2.08/5.0 = 0.416
So 0.416 * 10^-4 = 4.16x10^-5 in standerd form
or 0.0000416 in decimail
Jack (i think thats right anyway)
