When can you use MDAS rule?
Whenever evaluating expressions that do not have parentheses (brackets) nor indices.
How do you simplify algebraic expressions with brackets?
put the bracket before the answer and multiply it by the nth term
How do you silmplify algebraic expressions?
Multiply out all the brackets (parentheses) and then combine like terms.
Are there any uses for setting out bracket sums?
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 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 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 default order of evaluating expressions is BODMAS/PEMDAS. To change that order, parts of the expression need to be put in brackets (parentheses).
How do you show two expressions?
Put a comma between them. Better still, put them in brackets (parentheses) before that.
What is the opposite of factorising expressions?
Expanding Brackets

How do you simplify expressions with variables?
You multiply out brackets, remove common factors from fractions, combine like terms.

Put a comma between them. Better still, put them in brackets (parentheses) before that.
When evaluating algebraic expressions what is the order of operations?
BOMDAS Brackets (parenthesis), Of, Multiplication, Division, Addition, Subtraction
Where were brackets used first used?
Brackets were first used in ancient Greece by the mathematician Apollonius of Perga in the 3rd century BC. He introduced them to denote grouping in mathematical expressions.
How do you solve linear equations with bracets?
You simplify the brackets first and then you will have linear equations without brackets!
Why structure expressions in different ways?
The structuring of expressions is to arrive at the correct answer. Using the 'Order of Precedence' : 1. Brackets; 2. Powers and Roots; 3. Multiplication and Division; 4. Addition and Subtraction, ensures that the correct answer is arrived at.
Does a mathematical expression have to have variables?
Yes. Expressions cannot be expressed without variables. There are numerical expressions for ex. 2 + 3 is an expression without variables.
