As written, those are the same. For that sentence to equal 3, we need to use parentheses. (8 + 4) divided by 2 minus (1 x 3)
-- If they're being multiplied or divided, then they make a minus. -- If they're being added or subtracted, then they can make either a plus or a minus. It depends on which one is bigger.
Why don't you figure it out yourself
By factoring I get x-3 divided by x+3
It's one !

the answer is one (1) couldnt you have just used a calculator?!?

2 - (20/(1/3)) + (1/4 x 7) = -56.25
Commutative, not communtative The mathematical property of being able to change the order of the numbers and not change the answer. A plus B equals B plus A (1 plus 3 equals 4, 3 plus 1 equals 4) A times B equals B times A (2 times 5 equals 10, 5 times 2 equals 10) Addition and multiplication are commutative operators A minus B is not necessarily equal to B minus A (6 minus 4 equals 2, 4 minus 6 equals minus 2) A divided B is not necessarily equal to B divided A (9 divided by 3 equals 3, 3 divided by 9 equals one-third) Subtraction and division are not commutative operators

No. You may be thinking of the rule that a minus times a minus gives a plus. So -1 x -1 = +1. Or you may be thinking of using two plus signs. E.g. 1 + + 1 This just means 1 plus the positive version of one. This is just one plus one.
