Simple function I am unfamiliar With.

I am looking for the function that will enable me to take two numbers from tab A, and get the sum on tab B. To be precise, I am on the "Ratios calculation" tab, I want take current assets (cell B16) and current liabilities (cell b44) from the "Horizontal Analysis" tab and divide the, for the sum in (cell C6) on the "Horizontal Analysis" tab. I vaguely remember having to entre something in (c6) to the effect of =1+b16/b44.
