The Mathematical Challenge 2019

Leave a comment

On Thursday 7th February, some of our Year 10 and 11 pupils took part in the United Kingdom Mathematics Trust’s Mathematical Challenge. The girls were given 25 challenging problems to solve in 60 minutes. No calculators were allowed, only a pen, a pencil and some plain paper. Their papers have been sent off to Leeds University for marking and we look forward to receiving their results soon!

Here are 2 questions from the challenge for you to try.

  1. What is the value of (7 – 6 x (-5)) – 4 x (-3) ÷ (-2)?

a. -17      b. -11   c. 31    d. 37    e.  43

2. Two numbers, x and y, have a product which is equal to their sum. Express x in terms of y.
