# How do you simplify 2[7(63div7) + 120] - 152?

Jun 29, 2015

I found $214$.

#### Explanation:

$= 2 \left[7 \left(9\right) + 120\right] - 152 =$
Now deal with the multiplication of $7$ and $9$:
$= 2 \left[63 + 120\right] - 152 =$
add inside the $\left[\right]$;
$= 2 \left[183\right] - 152 =$
multiply the $2$ and subtract $152$:
$= 366 - 152 = 214$

You may notice (but I do not want to confuse you) that inside the square brackets you had:
$7 \left(63 \div 7\right) = 7 \left(\frac{63}{7}\right) = \cancel{7} \left(\frac{63}{\cancel{7}}\right) = 63$ immediately!!!
