Scientific notation is a way of expressing large numbers as a single integer digit followed by a decimal fraction all multiplied by a power of 10.

This is particularly useful when you don't need to see all the digits, but do need to know the overall magnitude of the number.

so rather than having:
31415926535897932384626433832795028841971693993751058209749445923078164062862090

you can write:
3.141593*1079

which conveys how big the number really is, and eliminates the extra digits that are usually not that interesting.

so what would this be (4x10 twoexponet)+(2x10 with a negative 3 exponet)=(6x10 with a negative 3 exponet) +(9 x 10 with a negative 4 exponet ) when you do find the answer which i`m pretty sure you can can you explain how you got this to me?

(4x10 with twoexponet) = 4*100= 400
+(2x10 with a negative 3 exponet)=+2*0.001=+0.002
=(6x10 with a negative 3 exponet)=-6*0.001=-0.006
I'm assuming this is a minus?

+(9 x 10 with a negative 4 exponet)=+9*0.0001=+0.0009

Now you just need to do the arithmetic
