10E5=100000; 10E-2=1/100. The order of magnitude is 10E(5-2)=1000 because 100000/100=1000.

However 9.982 is close to 10 so we can add 1 to the exponent: 10E(5-2+1)=10E4=10000 or multiply 1000 by 10=10000.

This is the order of magnitude, not the actual product.

(The product is 66520.048 which can be written 6.6520048E4, the order of magnitude being given 10E4 or 10000.)
