This video teaches how to calculate the number of studs needed for one wall.
A 20 foot wall will need 15 studs. Divide 20 by 4 = 5 or divide 20 by 2 twice 20 divided by 2 = 10 and 10 divided by 2 = 5. Next subtract the answer 5 from 20 and you'll get 15. 15 studs are needed for 20 foot wall.

How to Change Feet to Inches
Double the number to the right
37 = 7 + 7 = 14 (never carry a number over)
If the number is 4 or less round down to 0
34 becomes 30
If the number is 5 or greater round to 5
37 becomes 35
Always use 5 as the factor
What number times 5 equals the rounded number?

Note: for 16 inch tile, always use 6 as the factor and if the second number in the total square feet is zero you cannot use it however if the second number is above 0, use a decimal to separate them (250 becomes 2.5)
I will use 200 and 250 square foot rooms for my examples ...
