Question

Simplify this expression. Explain step-by-step the process. -12÷3•(-8+(-4)²–6)+2

Answer 1

Well so you have to go with pemdas. p parenthesis, e exponets,m multipication, d division, a add, s subtract. let start with the parenthesis which is 8 plus negative four to the secondpower minus 6. so negative 4 to the second power is equal to positive sixteen because negative time negative is equal to positive. so 8 plus sixteen is 24-6 is 18. negative 12 divided by 3 is negative 4.so negative 4 time 18 is negative 72 plus 2 is negative 70.the answer is negative 70

Answer 2

Using PEMDAS to answer this, the steps are:
Parenthesis first, so (-8+(-4)^2-6)= 2 
You now have -12/3 (2)+2 
Next is multiplication, so 3(2)= 6
Now you have -12/6 +2
Next is division, so -12/6= -2
Now you have -2+2
Add them together to get the answer of 0
