For those of you enjoying the brain teasing, here is today's first challenge.

I will not post the solution until tonight, to allow those in different time zones to have a go.

Different time zones😀 in my case it is cranking up my brain.


Do you need the workings still?

Marydoll Fri 03-Apr-20 09:17:20

Not yet, as that would give the game away.😉.😁

Assuming it’s a + sign ? In which case I stick with 40.

If it’s a x sign (it’s hard to make out on my phone) then 96.

Marydoll Fri 03-Apr-20 10:40:01

They are alll + signs.
No working please, at taht spols it for those who may want to try.

I will post the answer tonight to allow wila, who is the USA in lockdown to have a go!
