Well done to everybody who attempted last week’s question. Both Andie and Kasha commented with correct ways to make 99 and have won 5 HPs each. Go back to the challenge to see their correct answers.

And here is this week’s challenge…

Start the maze with no money. Go through the maze, collecting and losing your money as you go. You may not go through any box more than once, and can only go into a box through a gap, for example, you may not go from 5 to 6, or from 7 to 3.

For example:

Start -> Box 1 + £100 (£100) -> Box 5 lose £50 (£50) -> Box 9 + £10 (£60) -> Box 13 lose £10 (£50) -> Box 14 + £20 (£70) -> Box 15 lose £10 (£60) -> Box 16 + £30 (£90) ->

I come out with £90 at the end of the maze.

What is the biggest amount of money you can come out of the maze with? Comment on the blog below and show your working – the person with the biggest amount at the end of the week will get 5 HPs!

Well done to Charlie and Nicholas who answered the last maths challenge correctly with an answer of 27 triangles!

Here is your next maths challenge:

Where should you put plus signs between the digits below to make a total of 99?

9 8 7 6 5 4 3 2 1

For example, you could try:

9 + 8 + 76 + 6 + 5 + 4 + 3 + 21 = 126 (too high!)

9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45 (too low!)

There are two solutions to this problem but they are not easy to find so you may need to try a few different ways!

Have a go at this problem yourself and post your answer as a comment below.

Well done to Chloe Briers, Andie and Jaden who all worked out the correct answer of ’35’ last week – 5HPs to each of you!

Below is this week’s challenge. Remember to comment with your answer and come back to check if you are right.
