Just in case you are yet in need of understanding or a solution...
Negative exponents are the same as 1/positive exponent, so
1%5E-3-4%5E-2+=+1%2F%281%5E3%29+-+1%2F%284%5E2%29+=+1%2F1+-+1%2F16
Create a common denominator
%281%2F1%29%2816%2F16%29+-+1%2F16+=+16%2F16+-+1%2F16
16%2F16+-+1%2F16+=+5%2F16
Therefore,
1%5E-3+-+4%5E-2+=+5%2F16
