Those aren't "problems"; they are numbers. What is the question?

1E+6 = 1000000.0
2.3221E-4 = 0.0002322
you should be able to figure out the others from that.

1E+6 = 1000000.0
2.3221E-4 = 0.00023221
5E+4 = 50000.0
-1.789E+2 = -178.9
here E mean nothing but Exponent(Exponent to 10 ).
1E-6 means 1x(10 power of 6)
just like this
-1.789E+2 means -1.789x(10 power of 2)
If the above explanation doesn't satify ur needs ,Please let us know what u r expecting with details.
Thanks

O.k Rajendra Babu now this is more what I was looking for an explanation! I knew the exponent part but glad you added that makes a good referance. The parentheses they would mean I'm guessing that you would work the power out first? Let me explain it to you the way it was explained to me. I was told that E was an exponent so you should multiply that number by ten then take that number to the power after the plus sign. I guess my question was; Do you divide on negitives and multiply on positives? Following are my answers to the problem a or you tell me which one is correct or explain to me why there would be a decimal point ok? Where did you get the decimal from???
A. (1.) 10000000 (2.) 362797056 (note I am confused where you got the decimal from?)
1= 1x10<HTML>6th if this is not an html forum ignore this explanation. 2. 6 to the tenth power times one.
Im going to pause here and see what replies I get before I keep going.

Both the previous replies are correct - A is 1000000, also written as 1000000.0 You are confusing 106
with 610 (actually you have calculated 611 for some reason). Here is a link for you to practice with. Good luck.

Hi Frank,
Let me explain by steps.
A. 1E+6 = 1 x 10 ^ 6 = 1 x 1,000,000 = 1,000,000
B. 2.3221E-4 = 2.3221 x 10 ^ -4 = 2.3221 / 10 ^4 = 2.3221/10,000 = 0.00023221
C. 5E+4 = 5 x 10^4 = 5 x 10,000 = 50,000
D. -1.789E+2 = -1.789 x 10^2 = -1.789 x 100 = -178.9
