In the case of (x)(y) it is just multiplication of two variables.
I think you mean parentheses. Parentheses are ().
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.
40 years as a mathematician and I have never seen them in parentheses!
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)
To use the distributive property to remove the parentheses in the expression ( (y + 5) \cdot 10 ), you multiply each term inside the parentheses by 10. This gives you ( y \cdot 10 + 5 \cdot 10 ), which simplifies to ( 10y + 50 ). Thus, the expression without parentheses is ( 10y + 50 ).
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
"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.
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.
Function.
Parentheses are brackets which are rounded kind. Like the one below: ( ..... )
It means love. (L) on MSN makes a smiley face that looks like a heart.
Anything within parentheses should be calculated first.
