Hi Dan,

My computer doesn't have the symbols for math but it is the second problem you listed. I am also trying to find the square of 1/6 and 2/5

Thank you for your help 14 + 3squared

My book says 21 but I can't follow it. - Jul 2nd 2006, 11:21 AMSoroban
Hello, duckpluckie!

Use ^ for exponents . . . and use LOTS of parenthese.

14 + 3^2 . . . means: 14, plus 3² . . . or 14 + 9 = 23

If you want "fourteen plus 3,**all**squared", write: (14 + 3)^2

"14 plus 3 squared divided 6: 14 + 3²/6 = 14 + (9/6) = 14 + 1½ = 15½

If you want "fourteen plus 3 squared,**all**divided by 6", write: (14 + 3^2)/6

but it is the second problem you listed: $\displaystyle \,\frac{14\,+\,3^2}{6}$

My book says $\displaystyle 21$. .**?? . . . no way!**

$\displaystyle \frac{14\cdot 3^2}{6}=\frac{14 \cdot 9}{6}=14\cdot\frac{3}{2}=21$
