Mental Maths Test 2

Here is the test I promised today. I hope you can understand it all as my nose is still blocked up. In English we do not say that our nose is constipated. Constipated in English is when you cannot go to the toilet so please be careful with this "false friend".
In question 2, the word is HALVE (I found it difficult to breathe when saying it).

Good luck with your mental maths revision!
See you tomorrow!
