In the case of (x)(y) it is just multiplication of two variables.
I think you mean parentheses. Parentheses are ().
40 years as a mathematician and I have never seen them in parentheses!
If you mean y/2 + y (without parentheses), y/2 is the same as (1/2)y, and y is the same as 1y. You can use the distributive property to combine this; in this case, the result is (3/2)y.
two numbers in parentheses, separated by a comma are generally coordinates on a cartesian plane (x-y graph) and appear in the order of (x, y)
Function.
Always start with the innermost parentheses and work outwards. EXAMPLE : y = [-7 + √(3 + 13)] ÷ 2 y = [-7 + √16 ] ÷ 2 = [-7 + 4 ] ÷ 2 y = -3 ÷ 2 = -3/2
Yes you can. In algebraic problems, you see them quite often. Example:2x+4(y(2-7))-2This means that you first must subtract 7 from 2, and thenmultiply it by y.
Parentheses are brackets which are rounded kind. Like the one below: ( ..... )
"And forgive/excuse (me) I am (a) very curious (person)." The words in parentheses are not specifically part of the sentence above but they are implied.
It means love. (L) on MSN makes a smiley face that looks like a heart.
Anything within parentheses should be calculated first.
