I'm very, very new to Excel, and I need to create my own BMR (Basal Metabolic Rate) calculator for a project at work. I'm very confused by the formula builder.

Here's the formula:

BMR=
Women: 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years)
Men: 66 + (6.23 x weight in pounds) + (12.7 x height in inches) - (6.8 x age in years)


I don't understand how to set it up to make the proper calculations. Is there a step by step tutorial for this?

Thanks in advance!

P.S. - I'm using Excel 2008 for Mac
