are you doing the multiplication by hand?

When you get time, this might help http://www.khanacademy.org/math/arithmetic/decimals/v/mulitplication8multiplyingdecimalsoldvideo but 1.08 * 9.3 is not 9.944

ok i to 10.044 x 10 to the 6 but the real answer is 1.0044 x10 to the 5...

10.044 x 10^6 that is correct. but you want it in "standard" form. 10 is too big so divide 10.044 by 10 (make it smaller) to compensate, make 10^6 bigger by 10 (multiply by 10 which means add 1 to its exponent)

tonipoo610 Group TitleBest ResponseYou've already chosen the best response.0
so you have to add one or am i correct?

Did what I wrote not make sense? think about this: you have 10.044 x 10^6 we can multiply by 10/10 (ten divided by 10 is just 1) 10.044/10 x 10 x 10^6 10.044/10 is 1.0044 10^1 x 10^6 is 10^(16) or 10^5 so the final answer is 1.0044 x 10^5

so you can't have a number less than 1 or greater than 10???

phi Group TitleBest ResponseYou've already chosen the best response.1
you could, but it would not be in "standard form" if you had 0.001 you would multiply by 1000 (or just count 1,2,3 how many spots you move the decimal point). then you would compensate by multiplying by 10^3 1.000 x 10^3

ok i new that i am just learning that .0001..you would go to the right 4 times and you would get 1 x 10 to the 3

phi Group TitleBest ResponseYou've already chosen the best response.1
you mean 0.0001 is 1 x 10^4
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.1
0.0001 x 10000 /10000 or with exponents 0.0001 x 10^4 * 10^4 (0.0001 x 10^4) * 10^4 (0.0001 x 10000) * 10^4 1.0 * 10^4

ok got it

phi Group TitleBest ResponseYou've already chosen the best response.1
good. otherwise you won't understand the national debt, which needs scientific notation...

tonipoo610 Group TitleBest ResponseYou've already chosen the best response.0
yup! thxx

tonipoo610 Group TitleBest ResponseYou've already chosen the best response.0
ooo haha i just realize that 0 is bigger than 1 so when you have to compensate you would just add 1 that also goes with positive exponents right?
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.1
yes, 0 is bigger than 1. but 0 is neither positive nor negative. and of course 10^0 is the same as 1, so people generally don't use scientific notation when the exponent is 0 who would want to write 2 x 10^0 when 2 is all you have to write?
