^ in a formula (XP & 2003)
I ran across a formula as follows "+246*(1+.15)^5*200" . What function does the ^ perform in the formula? I never saw it used before.
Thank you.

Re: ^ in a formula (XP & 2003)
^ means "to the power of". For example 3^2 means "3 to the power 2", conventionally written as 3² (which equals 3*3 = 9), and 2^3 means "2 to the power 3", conventionally written as 2³ (which equals 2*2*2 = 8).

Re: ^ in a formula (XP & 2003)
Thanks for the primer in the use of ^ the exponent sign. However, I still cannot figure out the formula in the cell which reads{=246*(1+.15)^2*500} . Does this mean that the (246 *1.15) to the power of 2 and the product of this formula is 80,032.41. Then multiply the product of 80,032.41 by 500. Is this the order of calculation? However, the answer came out to 162,677.50.
Also, Why does the formula have the { before and a }after the formula.
As always, Thank you

The power operator ^ has precedence above the muliplication operator *, so in your formula, (1+.15)^2 is calculated first, and the result 1.3225 is multiplied with both 246 and 500, giving 162,677.5

Re: ^ in a formula (XP & 2003)
Broken out it is
1.15² * 246 * 500 =
1.3225 * 246 * 500 =
1.3225 * 123000 =
162667.5
The { } indicates it was entered as an array formula Crtl+Shift+Enter to confirm the formula instead of just Enter
This
<hr>(246 *1.15) to the power of 2 ... multiply ... by 500<hr>would be
=(246*1.15)^2 * 500

<hr>Why does the formula have the { before and a }after the formula<hr>The squiggly brackets are indicative of an array formula. A primer on array formulas can be found on Chip Pearson's website.Regards
