Yes, I know I always tell Wyatt one post per day but I just couldn't help posting the next clue(s)!!!!!! Here they are:

9x?=9
? is the square root of 1
?+?+?+?+?+?+?+?+?+?+2=12
What is '?' can you figure it out? I hope so because to me these questions are easy!

P.S Sorry if you are not good at maths.

P.S.S Shanti, Holly & Amy ur all older than me so you will probably know the answer to these qustions if any of these questions are wrong please tell me.
