I need to know within like 3 hours for an algebra regents.
More just a convention. Brackets as such have nothing to do with algebra. I would assume the round brackets are considered first, then the square brackets, when doing operations. But apart from this, it hardly matters. There are curly brackets as well. What happens with these?
I just saw this question, sorry it wasn't in time for the Regents. [ ] -- Those symbols mean including or Greater than or EQUAL to, or Less than or EQUAL to. ( ) --- Those mean not including or Greater than or Less than Example: In interval notation, 1 x 5 would be written like (1, 5]
in equations there is almost no difference between round and square brackets. take this equation for example: 5* [ 6x^2 + (3x+2)^2 ] 1 the brackets are used the same way as round brackets, they indicate to which the 5* applies. by using square ones for the second pair, you cannot mix up the brackets. in geometry we use brackets as well. the round ones are used to indicate we are talking about a point for example (1,2). this is the point where x1 and y2 the square ones are used for intervals. for example ]3,5] the variabel is greater to 3 and smaller or equal to 5.
In algebra: Round Brackets are used first and are called parentheses ( ). These are usually used to enclose negative terms with exponent like (-3)^5 etc. Square brackets are used after using rounded brackets. These are used to enclose the terms having twice power like [(5)^2]^4 etc, also they are used to enclose several terms like [(x+2)^2 + 4y].
