Maths O Grade exam questions

Here are some examples of questions that teenagers were required to tackle in their maths O Grade exam - can you answer them correctly?

1.) Question One

Question One

2.) Question Two

Question Two

3.) Question Three

Question Four

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.

0 - 0 : Pay attention at the back!

1 - 2 : Done your homework?

3 - 3 : Maths genius!
