Special interest

Working as a team we needed to use four 4's and any operation to make the numbers 0 - 20...

We could easily make 16
4+ 4+4+4 = 16

Other numbers were more difficult and we learnt the importance of BODMAS - the order of operations as well as the square root of numbers.

    The way I figure problems out is by people explaining,or sometimes the answer just eventually pop up in my head if I think deeply.Sometimes they give me a example then I have to use that example to figure out the problem.Square Roots are when you times a number by itself.

  5. I had fun When I did 4 four's, although I did struggle a bit but struggling makes your brain grow.There are easy numbers to make and hard numbers to make.

    Trying to make numbers 0-20 only using the number 4 was hard. I thought I was never going to get an answer but I was wrong. I got some answers most kids would be hopeful to get but would'n.
