(x+y) is the same as x+y
3(x+y) is 3 times as much. You multiply both x and y with 3 = 3x+3y
3(2x+4y) is the same as 3*2x+3*4y = 6x+12y
This is the general start of how to "solve" and do calculations with parentheses.
I am sure other people can add more examples with higher difficulty

solve the top and bottom first, as if each were in parentheses. Then Divide the numerator by the denominator
You square the number in the parentheses.
Parentheses are the following symbols: ( & ). These are parentheses. These help to do equations for example : 3+2x3=9 u are to put the parentheses or the backetts or the {} to help solve the equation so this is the way to put them in : 3+(2x3)=9. Hope This Helps!
18=3(3x-6)
you use PEMDAS which is parentheses exponents multiplication and division from left to right addition and subtraction from left to right
Parentheses is when you are doing an equation, and you solve the problem.

understand, plan, solve,& check
18=3(3x-6)
It means you have to solve the problem in parentheses first. ex: 2X4+5= 13; 2X (4+5) = 18. The answer is different because you have to solve the problem in the Order of Operations. 1) Parentheses 2) Exponents like 22 3) Multiplication 4) Division 5) Addition 6) Subtraction PEMDAS or Please Excuse My Dear Aunt Sally.

3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12
To use the distributive property, multiply the term outside the parentheses by each term inside the parentheses. For example, in the expression ( a(b + c) ), you would calculate it as ( ab + ac ). This property helps simplify expressions and solve equations by distributing a common factor across terms. It's particularly useful when dealing with addition or subtraction within parentheses.
Binomial Expansion makes it easier to solve an equation. It brings an equation of something raised to a power down to a solveable equation without parentheses.
(43 - 19) + (16 - 14)(4)= 24 + (2)(4)= 24 + 8= 32
