like your new avi, by the way...
( it is new, right?- or am I not very observant? )

It's 'new' - well, it's me 50 years ago.
Don't know if I like it yet though - might go back

No, I think you are wrong.
The original equation was stated without using brackets, so the equation is solved by doing everything in a strictly linear fashion.

7+7÷7+7x7-7 = ?
7+7=14÷7=2+7=9x7=63-7= 56
See?
(you can't add the brackets in later, that's not fair as it changes the outcome) 😉

Hey, I can select my own post as a "solution" . . . cool. 😉

The answer is 50 according to the mathmatical order of operations known as B.O.D.M.A.S. which operates irrespective of brackets.

Thanks Gkam. I finally get it! I am hopeless at maths and didn't understand the BODMAS thing properly before but now I see how it's done.
Thank goodness my boys were good at maths and didn't need help with homework.

Im with you J*oono..
When I was at school, it used to do my head in trying to work it out, but once you see the rule laid out, its like a fog lifted..my son is a wiz with maths and physics- way way above my head, but he sees relationships and remembers rules with ease..and he explained the BODMAS rule to me.
Very humbling when your young son explains a mystery to you in a simple way which blows your mind...
