I have an expression i must evaluate and it looks like this:[-3^2-(-2)] [sq.root of 16 - 2^3] Im not asking for it to be solved, for I'd like to do that myself for practice, but it would be nice :) but what do i do with those brackets, yo? H.E.L.P ME?
They are just delimiters. [.] is only a form of bracket distinquishing one complete expression from another.
The bracket is equivalent to the parentheses. It is simply a way to discriminate between the order of solving the problem. Treat them as parentheses.
They represent the mathematical operations that occur inside them. For example if I wanted to multiply 2 times 3 times 5 it would look like this 2*(3*5)30
They are used the same as parentheses. Both are referred to as grouping symbols. In Order of Operations, expressions inside parentheses or brackets get evaluated/simplified first, from inner to outer if there are multiple sets layered. In this problem you evaluate each expression inside the two sets of brackets. They also mean multiplication if they are ( )( ) or [ ][ ] (the brackets in this problem are that way) or a number and one set of parentheses/brackets. Multiply together the expressions inside the sets of parentheses/brackets after evaluating them.
its just for clarity that the Brackets are different ( [ { can be used as the LEFT delimiter )]} are RIGHT delimiters [-3^2-(-2)] [sq.root of 16 - 2^3] X * Y X -3^2 -(-2) -9 + 2 -7 the brackets should be used to remove ambiguity then it is to work from the inside out Brackets are containers Y (16-2^3) ^(1/2) (16 - 8) ^(1/2) 8^(1/2) [2^3]^[1/2] 2^[3*(1/2)] 2^(3/2) [-3^2-(-2)] [sq.root of 16 - 2^3] -7 * 2^(3/2)
