Brackets tends to be an English expression, Parentheses is used in the USA and elsewhere. Technically, Parentheses are rounded brackets but this really doesn't matter in mathematics as long as different shaped brackets/parentheses are used to separate the various elements of a mathematical expression.
To expand three brackets, expand and simplify two of the brackets then multiply the resulting expression by the third bracket. (FAIZAN BHAI GHAZI)CHANNEL
How do you write an expression
Usually they are opposite processes. Factorisation is taking an algebraic expression and partitioning it into factors in brackets (or parentheses). Expansion is taking such brackets and multiplying them out to a simple - if lengthy - expression.
6(x + 7) = 6x + 42
how do you write an expression with three terms
That will be difficult to answer without seeing the expression. Best guess: One less than the number of terms in the expression.

Yes. The default order of evaluating expressions is BODMAS/PEMDAS. To change that order, parts of the expression need to be put in brackets (parentheses). Yes.

The answer depends on what expression you do have and for what kind of shape!
You can always write a numerical division expression as a decimal.
It means calculate the value of the expression (i.e. simplify) by mutiplying. So, as a completely random example, if you have an expression like: x(x + 1) then, in this particular case, you would multiply what is outside of the brackets by each term inside the brackets to get: x2 + x.
