  1. 1. (a) variable — Such a letter is a variable.
  2. 2. (b) 3x — 3 × x is written 3x.
  3. 3. (c) 10 — 6 + 4 = 10.
  4. 4. (d) 5 — The number multiplying x is 5.
  5. 5. A letter that stands for a number that is unknown or can change.
  6. 6. 2x + 4.
  7. 7. In algebra we use a letter, such as x or n, to stand for a number that is unknown or that can vary — this is called a variable. We then combine letters and numbers using the usual operations to form expressions that describe situations. For example, 'three times a number' is written 3x, 'five more than a number' is x + 5, and 'a number halved' is x/2. The letter behaves just like a number, so 3x means 3 multiplied by whatever x stands for. This lets a single short expression describe a rule for many different values.
