2(3-4)+ 6/3-300/2 (squared)2(-1) + 6/3-300/2 -because 3 - 4 = -1-2 + 2 - 300/2-6/3 = 2-150 -you get -150 because when adding -2 and 2 it is really like you are subtracting becasue there is a negative number. So you are left with the problem 300/2 which is just 150. The reason it is negative is because you have a subtraction sign or in this case a negative sign before 300/2If you are supposed to square the whole problem then I think it would be, 22500. I'm just a little confused on what you mean about the squaring. If you don't square then your answer is just -150.Hope this helps!
