Math is a singular noun. Maths is a foreign word used when the speaker wants to appear silly and/or pretentious.
Then why is mathematics plural?

irrelevant. I’m not, and never will be, on the moon.
Exactly. It doesn't have brackets or parathesis around 2(2+2). If it did have brackets it's a different question. In my opinion you cannot assume they meant to put brackets around 2(2+2). If you want the answer to be 1 the equation would be 8/(2(2+2)), but that is not what is written.As shown it’s really unclear. Without brackets around the 2(2+2) it is 16. Assuming brackets it’s 1. I’ve seen this many times as an engineer where someone implies a math operation but does the math wrong anyway.
The order is PEMDAS: Parentheses, Exponents, Multiplication, and Division (from left to right), Addition and Subtraction (from left to right).
But since we’re arguing about technically correct stuff, “six times less than,” say, 200 pounds would be a negative 1000 pounds. Did you mean “one sixth the weight on earth”?Some hospitals will weigh you in kilograms.
And going back to the original (sarcastic) comment, your weight on the moon will be six times less than on earth, but your mass will stay the same.
Thank God pilots don't need to know anything about math.
sics monts ago I culdt spelt pilot, now eye ist won...

Amazing how they spell so poorly that it actually spells something else.Georgia Tech Flying Club.
Agreed. I believe the lack of clarity results from the way it is notated. If it were written as:The parentheses around 8/2 changes nothing. The answer is 16 with or without them.

The linear way of that is 8/(2(2+2))Agreed. I believe the lack of clarity results from the way it is notated. If it were written as:
8
______
2(2+2)
then the answer is obviously 1. The linear method of writing things out is where we run into issues. For instance, we write the fraction for 0.5 linearly as 1/2 even though technically it is

I dunno ‘bout programming because I ain’t a programmer other than playing with Basic many moons ago. But I do have a few elaborate Excel spreadsheets I’ve made. If I do sumpin like 2(blah blah) it says unable or something like that and offers up a suggestion like 2*(blah blah) will work. Don’t make no sense to me. I’d expect Excel to be smarter than that.Anyone with a computer programming background will have no problem with linear expression. Of course the OP formula won't evaluate in most languages because the multiplication operator is missing.

As an aside, they have a series of PPL prep videos. I am going to use one of them for a ground school segment I'm teaching in the spring on systems. The graphics are great and it really explains how an aircraft engine works.So, an ERAU graduate!
