Absolute Value
How far a number is from zero.Example "6" is 6 away from zero, but "-6" is also 6 away from zero.So, the absolute value of 6 is 6, andadf the absolute value of -6 is also 6.The symbol "|" is placed either side to mean "Absolute Value", so we can write: |-6| = 6

Brackets
Brackets are symbols used in pairs to group things together. Types of brackets include: parentheses or "round brackets" ( ) "square brackets" or "box brackets" [ ] braces or "curly brackets" { }"angle brackets" < >Example: (3 + 2) x (6 - 4) = 5 x 2 = 10The Parentheses group 3 and 2 together, and 6 and 4 togetherNote: Angle brackets can be confusing because they look like the "less than" and "greater than" signs.

Value
Money how much something is worth.Mathematics the result or 'output' of a calculation.Example: 3 × 4 gives the value of 12.
-
Constant
A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constantsIf it is not a constant it is called a variable.

Variable
A symbol for a number we don't know yet. It is usually a letter like x or y.Example: in x + 2 = 6, x is the variableIf it is not a variable it is called a Constant
