Answers

  1. 23 x 48 x 2.5 = 2760d = £11.5 (you divide by 240) - This translates into 11 pounds 10 shillings. Those of us who don't remember pre-decimalised currency might not know that there used to be 240 pennies in the pound. And the calculation would have to be made without a calculator!
  2. (2 x 16) + (3 x 4) + 1 = 45 in base 10. Expressing numbers in a different base was never part of the new Standard Grade syllabus. There is, however, a link between binary numbers and computer systems, so this is now part of computing studies.
  3. The magnitude (or length) of a vector is the square root of the sum of the squares of the components. Vectors now appear in the Higher and Advanced Higher Mathematics courses.
