Hi everyone.

I'm currently tutoring a 15 year old maths student and his teacher has set an assignment question that's a bit wierd.

'Using four 6's and the operations (plus, minus, divide, multiply and brackets) make equations equal to the numbers 1 through 9)

The following examples are given

66/66 = 1

6/6 + 6/6 = 2

(6 + 6 + 6)/6 = 3

I've got answers for all except for 9. Anyone know how you could make an equation equal to nine?

Secondly, this is supposed to be a piece of assessment testing basic algebra. I really don't see how this problem can be done algebraically. Am i missing the point of what this teacher is trying to do here?
