I need a formulaa to track weight loss with a total for pounds loss.

The key to these type of problems is to view it as a game of cracking a secret code. It is important to think through the problem word-by-word to translate that word into its symbol (or number). Start left to right and replace words with numbers or words:

Nine more than a number would become:

Nine more than a number

9 + x

Words such as "more than," Added to," "plus," etc. are a plus sign

Words such as "decreased by," minus," "less," (note this is not "less than") mean a subtraction sign.

Words such as divided by and times are replaced by a division sign and a multiplication sign respectively.

They key here, again, as is NOT commonly taught in our schools today is that these are NOT magic formulas. Math was a means to try to show, on paper, real-life problems. On paper they were easier to solve.

A problem such as "9 more than a number" would the real life euivalent to saying something such as you already spent some money ( "a number" of dollars) and then spent 9 more dollars. This is not a very practical situation as you normally know how much you did spend to begin with.

However, this statement WOULD be useful for saying something like:
1. Let' say I spent 1 doallar and then 9 - how much did I spend?
2. Lets say I spent 2 dollars them 9 - how much did I spend...
etc.

Again, this may not seem too practical, but omputers HAVE to be fed statements such as this when they calculate stuff for us.

Also, the main idea in algebra is NOT to make you sit in a classroom and b bored to tears with a bunch of formulas. It is to have your mind practice through the ways of thinking that an UNDERSTANDING of math problems bring. We will never have someone walk up to us in the mall and ask what is "9 + x if x is 10?" But we will have to do think such things as "If I spend 9 more dollars, how much will I Spend total?" Here your mind is using the concept of 9+x.

Start by identifying the letters. Then arrange them so they make a nine letter word.

2 vowels and 1 semivowel. In a nine letter word, that makes a lot of consonant clusters.

Two such words are "annuities" and "insinuate".

(a ± b)³ = a³ ± 3a²b + 3ab² ± b³

(a ± b)4 = a4 ± 4a³b + 6a²b² ± 4ab³ + b4

a² - b² = (a - b)(a + b)

a² + b² = (a - bi)(a + bi)

a³ - b³ = (a - b)(a² + ab + b²)

a³ + b³ = (a + b)(a² - ab + b²)

a4 + b4 = (a² + 2½ab + b²)(a² - 2½ab + b²)

an - bn = (a - b)(an-1 + an-2b + ... + bn-1), for n even

an + bn = (a + b)(an-1 - an-2b - ... - bn-1), for n odd

Nine to the second power is nine times nine which is 81, not eighteen.
