Lemme think.

And if you'd care to take a dare, I'll make a bet with you.

Re: Make 28

2 + 8 = 10 x 3 = 30
- 5% = 28.5

That's the closest I got.

Re: Make 28

(5 - (3/2))*8 = 28.

Go me.


Why did the vector cross the road?
It wanted to be normal.

Re: Make 28

I do re-read my posts but can never be asked to edit them. My post is supposed to say:

Look Zach, you're not the best at maths, just face it.

Re: Make 28

I assumed that when "yvonne" said %, she meant ÷, because % can't be used in any useful way anyway.
