I am changing my answer to 19. Paradolia led me to see 4 table legs instead of the actual 3.

Been too long since math class
I knew there was an "order of operations", just couldn't remember it.

Do not agree with silly chart. With no brackets or other distractions, operations go left to right, add then multiply. Answer is 35. Unless you are from a country that writes right to left.

Wrong, Wrong, Wrong. I do it my way. I'd get out my old school books but Mom threw them away 60 years ago when I joined the Military.

Hey Sargent (ohh - ?Private - did I promote you?) - This is the Colonel (26 years). There is no 'your way', there is only the 'Company' way. We have no need of books any more - not since Wikipedia and ChatGPT. Again - this is a teachable moment. Free education lest you appear uneducated and thus discredit your unit.Wrong, Wrong, Wrong.

Guys, guys - what's going on? I posted an interesting puzzle (as I do from time to time) and it gets 90% great reactions from members who enter into the spirit of the thing and have ago. Now that's great and why not, win or lose who cares? it's not a competition - it's just a puzzle I share for your enjoyment - it's just a bit of fun and because I enjoyed the puzzle I decided to share it with my fellow site members. Because I often don't get it right first time I am reminded of my days in school and university (a long time ago) and often surprise myself either by getting it right or reminding me where I might have gone wrong. Adults often scan a page and don't look in detail as a child might so we often assume and miss the detail - this post received a lot of interest so I'm happy. Merry Christmas or/and Compliments of the Season.
