The last term is the easiest, 4 × (2) = 8. For the middle term you need first to evaluate what is inside the parentheses, 6  9. But 6  9 = 3 and thus (6  9)/(3) = (3)/(3) = 1. For the first term you evaluate the exponentiation (power) first and then the negative. So 2^{2} = 4 and hence 2^{2} = 4. To get the final result add 8, 1 and 4. Penny
