when writing scientific notation, there must be one number to the left of the decimal point.
To achieve this in this problem, you need to move the decimal point 3 times to the right.
because you are moving the point to the right, the exponent will be negative.
*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*
therefore you answer should be written as:

The lowest number of strands usually seen is 7 ... one in the middle
and 6
surrounding it.
The next level up is 19, which is another layer of 12
strands on top
of the 7.
After that the number varies, but 37 and 49 are
common, then in
the 70 to 100 range (the number is no longer exact).
Even larger
numbers than that are typically found in very large
cables.
Helen should of put 0 first, because if you're gonna divide, you need to put the product first, then one of the factoes.
So instead it should be 0÷(-7)=0
