answers to the sum of fours

And I'm finally back with the answer to that series of sum's in my latest post. To remind you the challenge was . How do you create the numbers 1,2,3,4,5,6,7,8,9 & 10 only using the following digits 4, 4, 4, 4, +, -, /, x So how did you go? I managed to do from 1-9 but stubbled with 10. Can you do 10? Here they are: 1=4/4x4/4 2=4/4+4/4 3=4-4/4 4=4/4x4 5=4/4+4 6=4+4/4+4 7=4+4-4/4 8=4+4 9=4+4+4/4

And you thought using 4's in a sum was easy!

Do you think that adding, subtracting, dividing and multiplying by 4 is easy? If you do then keep reading, and if not then just keep reading for the fun of solving a problem that has taken me ages to figure out. Here it is: Using only four 4's, addition, subtraction, division and multiplication, try and make all the figures (numbers) from 1-9 and this time I'm not going to give you any help. I'll post the answers soon.
