  1. 3. A rule or fact written with mathematical symbols. It usually has an equals sign and two or more variables. For example A=πr² is the formula for the area of a circle where A is the area and r is the radius
  2. 4. Finding what to multiply to get an expression
  3. 8. A fraction in which the numerator (top number) is smaller than the denominator (bottom number)
  4. 14. A reduction in price
  5. 15. 1/number. To find the reciprocal we divide 1 by the number. This can also be thought of as ‘flipping’ a fraction
  6. 16. A fixed value. For example in 4y - 7 = 5, -7 and 5 are constants. This is also known as a ‘constant term’
  7. 17. A list of numbers in a special order
  8. 19. The reduction in value
  9. 22. Expanding is multiplying to remove brackets
  10. 24. A mixture of a whole number and a (proper) fraction
  11. 26. A fee paid for services, usually a percentage of the total cost
  12. 28. When quantities have relative size. For example 2 in 4 is proportional to 1 in 2
  13. 29. Numbers, symbols and operators (such as + and x) grouped together to show the value of something. For example 4y - 7

  1. 1. A reduction
  2. 2. A fraction in which the numerator (top number) is larger than the denominator (bottom number)
  3. 5. Percentage, written %, means out of 100
  4. 6. A term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or - symbols. For example 4y - 7 = 5, 4y, -7 and 5 are terms
  5. 7. A negative profit
  6. 9. Fractions which have the same value, even though they may look different
  7. 10. Income minus expenses
  8. 11. Income minus expenses
  9. 12. A symbol for a value we don’t know yet. For example in 4y - 7 = 5, y is the variable
  10. 13. Like terms are terms whose variables and exponents are the same. For example 7y and 4y are like terms, 8y²z and 2y²z are like terms
  11. 17. Rewriting an expression putting values where the variables are. For example in 4y - 7, we can substitute y=1, so 4 x 1 - 7 = -3, or we can substitute y=3a so 4 x 3a - 7 = 12a - 7
  12. 18. Numbers comparing the sizes of two or more quantities
  13. 20. Things arranged following a rule or rules
  14. 21. A number used to multiply a variable (written in front). For example in 4y - 7 = 5, 4 is the coefficient of y (the variable)
  15. 23. Income minus expenses
  16. 25. Goods and Services Tax - a 15% tax added to the price of most goods and services
  17. 27. A mixture of a whole number and a (proper) fraction
