I see the bottom line being 5 + 1 = 6, then 6 × 10 = 60
 
I dunno...Is it 5:00 yet? 🤓

To do it correctly, multiplication always comes before addition or subtraction within a math problem, so it should look like this:
 
5+(1x10).

You have to do the multiplication first

@Floyd :
 
Why?
 
Whatever. I was told there would be no math! Emoticon

A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

@Floyd I didn't notice the two servings! I change it to 60! Does it count that I got up at 7, clean my beach house after having 4 dogs there, packed up and drove home without having breakfast count or just my poor eyesight? These things are tricky.

I came up with 60 and my 13 yr old corrected me that i need to do the order of operation which is multiply first then add. 😂😂

So, now it is 15? My math skills must be leaving the building! This sounds too much like algebra. I didn't like it then and thought it had no use.

Yeah, my kid just schooled me on that, too (even spit out the Please Excuse My Dear Aunt Sally thing).
 
I knew that...I was just seeing if she was paying attention...
