it's not a matter of whether people can do math or not, just people not reading the badly written mathematical formulation in the conventional way. write it like 48/2*(9+3) and you will see people are better than math than this particular poll indicates. | ||

I almost always convert division to multiplication by an inverse and subtraction to addition of a negative, it makes situations like this less confusing. | ||

Division and multiplication are equal in priority so it is read left to right. 48/2*(12) 24*12=288 WTF are people thinking. Should they feel the same about your writing skills? It's a trick math question and some people will fall for it, calm down. | ||

only 54%??? C'mon guys! This is 4th grade stuff! Multiplication and division are equally important and those two are to be placed on order from left to right! | ||

But that's just a matter of convention. You just define stuff as you need, and as long as it's consistent it doesn't matter. Arguing about conventions is utterly stupid. | ||

Most get it right that the priority is the (9 + 3) = 12 and get this 48/2*12. There is a rule that allow you to switch the order of the numbers but only if there is only multiplication in it and frankly this is not the case. So 48/2 comes first and that gives us 24 and then we multiply 24 and 12 and get 288. Problem solved | ||

48 ÷ 2 * (9 + 3) = 48 ÷ 2 * 12 = 24 * 12 = 288 | ||

If you do it right you should find 288. But if u see the equation like this : 48 _______ 2x(9+3) you will find 2, which would be the right answer if the calcul was this : 48 ÷ (2(9+3)) | ||

The answer is 288, but the way it is written is really deceiving. It sets the equation up wrong in your head. | ||
