$- 14$ $-14$

$- 20 - 10 \div 5 + 2^{3}$ $-20-10÷5+2^3$

According to BIDMAS/PEMDAS, first you do the indices, then division, addition and finally subtraction. So:

$2^{3} = 8$ $2^3 =8$

Then do division of -10 and 5:

$- 10 \div 5 = - 2$ $-10÷5=-2$

Now the equation looks like this:

$- 20 - 2 + 8 \to - 22 + 8$ $-20-2+8 -> -22+8$

Now add them up:

$- 22 + 8 = - 14$ $-22+8=-14$
