What is "e"? What does it mean? apparently 66 times 6 times 6 is 3.96e2. What?????
e is a numerical constant, like pi. Here, it just means that the number here is appoximated, and you need to multiply the number by 10*2 (the same 2 in the e2) btw are you sure it was not e 3 or e 4? That number does't seem right.
66*6*6 = 2376
"e" stands for "exponent" or power of 10. So, in computer language: 1.23e10=1.23 X 10^10.
