2 to the 4th power -8 x2÷4 = ? The book gets 12 I get 0 what am I doing wrong please help

(2^4) + ((-8 * 2)/4) = 12

Step-by-step explanation:

2^4 - 8 * 2 / 4 = 12

First, turn the equation into this

(2^4) + ((-8 * 2)/4) = 12

Always do exponents, multiplication and division first

So, 2^4 is 16. Next do -8 * 2 which gets you -16, then divide that by 4 to get -4. Lastly, add on the 16 to the -4 to result in 12.
