Hi Melody,
I was willing to answer that thinking it had to do with Permutations but I didn't want to risk getting it wrong.
I don't understand.
Are you talking about factors or number that literally go in between.
-12 / -4
If I'm correct it should be unless you Times it 0.5.
But that should be correct.
What are you confused on. I try help if I know it.
No I didn't learn that at school.
But I have a simple idea of it and now I understand it.
Could I have a question on it please?
:)
im also confused with turning fractions to single fractions
1/a - 1/b + 1/c
Yes, when expanding the brackets the number outside will times everything on the inside but showing brackets just makes it easier instead of loads of *
2*4= 8
2*7=12. 8+12=20
I don't understand. After adding the brackets on the last one you expanded it out but you added 2..?
No I haven't done factorising at all at school.
But instead I read maths book at home for further education.
