What does -3.4 e + 38 mean? (in normal number terms).

"E" stands for exponent, specifically 10. If something says "E+38" (like in Microsoft Excel), that means 10^38 in scientific notation.  
Therefore, "-3.4 E + 38" means -3.4x10^38.  
The "+38" means there are 38 zeros following a 1 as the exponent. It also works with negative numbers. For example, E-3 equals 10^-3

since 500 is 5 with 2 zeros you can take away them and make it 3x5=15

then add the two zeros back again and you get 1500 so 1500 is your answer

hope i helped
