3 to the second power minus thirty divided by 3 divided by 5

I'd rather see you do it by hand MG,

you could check  your answer on the calc afterwards :)

$${{\mathtt{3}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{\frac{{\frac{{\mathtt{30}}}{{\mathtt{3}}}}}{{\mathtt{5}}}} = {\mathtt{7}}$$

3 squared =9 

9-30= -21

-21/ 3 = 7

7/5= ummmm..?

wait. 

-21/3=-63

-63/5 = ...

PS: i forgot my old answer when i got to this page all i saw was your comment.

But that is not right MG

You have to do both the divides BEFORE you minus :)

what is {21-3} divided by 3 to the second power
