Right, it's time for this week's MENTAL MATHS CHALLENGE. 15 questions for you to muddle over. But, just like with our quiz, we want answers ... and we want them NOW!
Just hit the play button in the audio bar at the bottom and listen up! Don't forget -- it's about accuracy, not speed.
HOW TO ANSWER:
OK, for answering, here are your options:
1. Get a sheet, or your Homework Club copy, and write down your 15 answers. Keep them safe until Friday, when we (you and I) correct them.
2. If you would like to enter the draw for the €25 voucher competition, imagine the comment box below is now your ANSWER BOX. Get typing, and don't forget to leave your name and email adress along with your answers.
Send this, share it, get your mum, dad, brother or sister to do it! Maths time is fun time ... and bragging time if you beat the rest!
DON'T FORGET TO COME BACK ON FRIDAY TO CHECK OUT ALL THE ANSWERS!
