So u use (PEMDAS) first you do (2+4) which is 6 then the exponent which makes that 36 because 6x6 is 36 then u divide 36 by 3 which is 12 then u do 60-12 = to 48 60-(2+4)²÷3 = 48 I’m pretty sure that’s the answer if it’s soppose to be negative then it’s -48 but I’m pretty sure it’s soppose to be positive I hope this helps
