This was quite a challenge and lots of you obviously had a really good go at it. These are from pupils at Moorfield Juniors.

Adam, Abbey and Gemma arrived at 12 like this:

Jimbo and Matt P worked out ways to get 15, 16 and 17:

Numbers 1-9 were a little harder but you coped very well! Among the correct solutions were these from Emma, Amy, Matthew, Hannah, Steven and Jenny:

• 4-4=0+4=4-4=0
• 4-4=0+4=4/4=1
• 4/4=1+1=2
• 4*4=16-4=12/4=3
• 4-4=0x4=0+4=4
• 4*4=16+4=20/4=5
• 4+4=8/4=2+4=6
• 4+4=8-4/4=1 8-1=7
• 4+4=8x4=32/4=8
• 4+4=8 ; 4/4=1+8=9

Well done for getting these, but could they have been written down in a slightly better way do you think?

Getting 10 was rather tricky. Pupils at Ysgol Gynradd found a solution but using square roots:

Square root of 4 + square root of 4+square root of 4 +4 =10 .
