simplify this.
7{[4(a-4)+16] - [2(3a-2)+2]}
:
start with the inmost brackets first, multiply what's in those brackets
7{[4a -16 + 16] - [6a - 4 + 2]}
:
Do the math inside the brackets
7(4a - (6a - 2))
:
Remove the inner bracket, a minus changes the signs
7(4a - 6a + 2)
:
combine the a's
7(-2a + 2)
then mult each term by 7
-14a + 14
