  • the rule that tells us the sequence in which we should solve an expression with multiple operations
    Order of operations
  • Describes two operations that are equally as important, i.e. can be done in any order

    Equal Priority
  • An index, or power, is the small floating number that appears after a number or letter. Indices show how many times a number or letter has been multiplied by itself.

    Indices
  • refers to the distance of a number from the origin of a number line
    Absolute Value
  • An operation reverses a calculation that has been completed by using the opposite operation
    Inverse
  • means changing the sign of the number and adding it to the original number to get an answer equal to 0.
    Additive inverses
  • when you enlarge a shape and each side is multiplied by the same number. This number is called the scale factor
    Scale Factor
  • To get this we divide 1 by the number.
    Reciprocal
  • are factors of a number that are, themselves, prime numbers. We can find these by creating factor trees
    Prime Factor
  • is the greatest number which divides each of the two or more numbers
    Highest Common Factor
  • A common multiple is a number that is a shared 
    multiple of two or more numbers. The 
    lowest common multiple (LCM)
     is found by listing the multiples of each number and circling any common multiples. The lowest one is the lowest common multiple.
    Lowest Common Multiple
  • Any number below zero is a negative number, negative numbers are always written with a - in front of them

    Negative Numbers
  • indicates the amount of a variable. No coefficient means that there is just 1
    Coefficient
  • - is a combination of numbers, variables, functions
    Expression
  • a mathematical statement that shows that two mathematical expressions are equal.
    Equation
  • means a mathematical expression in which the sides are not equal to each other.
    Inequality
  • Multiplying a number by a group of numbers added together is the same as doing each multiplication separately.

    Distributivity
  • refers to the process of simplifying an expression or equation by multiplying out brackets
    Expanding
  • the reverse process of expanding brackets. To factorise an expression fully, means to put it in brackets by taking out the highest common factors
    Factorising
  • an equation in which the highest power of the variable is always 1.
    Linear equations
  • HCF
    Highest Common Factor
