F+G:

Then, add the elements that occupy the same position:

Solve

So, we find the element at address h31:

In this case, position h31 is - 8.0
So first of all we can't start by changing them both into improper fractions
So it would be:
5/2 divided by 13/8
From there you would do 5/2 * 8/13 which could convert to
5/1 * 4/13 which would be 20/13

Three hundred nine million is in the millions bracket; wherein, three is in the hundred million place and nine is in the one million place.
fifty-eight thousand is in the thousands bracket; wherein 0 is placed in the hundred thousand place, five is in the ten thousands place, and eight is in the one thousands place.
three hundred four is placed as such because three should be in the hundreds place, 0 is in the tens place, and 4 is in the ones place.
------------------------(- K)-------------0-------------(+K)-----------------
K unit to the left of 0, means K is negative.
The opposite of (-K) is (+K), both are symmetric vs. the origin "0", then its location will be +K
It's pretty simple if you just read through it carefully. Here you go.
