Squared = times itself <br />
(that's not funny!)

if the 2 is a superscript (smaller size and placed on the top right of 15) then it's an exponent and alternate and hlp are right. 15 x 15 = 15^2

it's 15x15<br />
if it's a 3 on top of the 15 then it's 15x15x15

I think 15x15. The small number is an 'exponential'.

If your talking Algebra here, 15 to the 2nd power, which would be 15 x 15.

Its written as 15^ ( read as raised to ) 2 , ie <br />
15^2 = 15 * 15 = 225

it's 15 squared that means 15 times 15, the small number above and right tells you how many times you need to multiply a number by itself, 15 with the 2 would be 15X15, with a three would be 15X15 then multiply the result by 15 again and so on

I think you should divide the 15 by 15 then round up to the nearest 15 hundredth and add 15 more then reduce it to its lowest form.

I will say about another VERY HUGE MATH PROBLEM:<br />
Some suppose - I don't know WHY - they probably ARE VERY BAD IN MATHEMATICS, TO THEM<br />
10 > 12<br />
GIVE PRESENTS<br />
NICELY PACKED<br />
also 0 resources BECAUSE MATH RULES 3 YRS torture IS 3 MINUTES TO SOME<br />
MANY MATH PROBLEMS THERE EXIST TOTALLY UNRESOLVED<br />
WORLDWIDE<br />
