Is this question true or false? (a+b) + c = a + (b+c)?

Is this equation true or false? Thank YouIs this question true or false? (a+b) + c = a + (b+c)?
it's true.


if you've a question, put numbers in and do the math.





what parenthesis do is allow you to change the order of operations when the natural order is not what's wanted. eg,





2+3*4 you multiply before you add.


(2+3)*4 this requires the parenthesis because i want to add first.


if you're just adding, the sequence in which you add doesn't make much difference.


in fact, when i'm adding multiple numbers, i sometimes do them out of sequence, because it works out easier if i do that.Is this question true or false? (a+b) + c = a + (b+c)?
true because you do parenthsis first thats all there doing is saying to add them first so that would be true!
True. It shows the associative property of addition.
True. This is an example of the distributive property.
true. if you have problems with questions like this one, you can always but numbers in and see if its true or false
its true,if a=1 b=2 and c=3 the problem would look like (1+2) + 3= 1+ (2+3), 6=6
True
