I say 16. I usually get these in a second or 2 then skip to the end to see if my answer was correct. As I get older my trust in my answer is not as much as it was 40+ years ago when I first learned this.

[russelllomando]

got 16 2 seconds thanks for the fun

Just a random thought, and I highly doubt that the world is going to change one iota because of anything I say, but it strikes me that it would be useful if there was a semantic difference between ÷ and /.
/ could mean "everything before this is the numerator and everything after it is the denominator."
÷ could mean "divide the term immediately before this by the term immediately following it."
Or, if we prefer ascii characters for convenience, we could use / and \.

I dont like error-prone mental math.
I used pencil and paper for noting down intermediate results to reach the main result.
18 : 3 x 2 + 4 --> Using parentheses to prioritize according to PEMDAS rules
4 +[(18 : 3) x 2] --> Work it from the inside out : (18 : 3) --> [6 x 2] --> 4 + 12 --> 16 ---> Main result

Can you please cover a video on how to use a tape measure and speed square. I get the inches and feet but not 1/8 1/4 5/8 3/4 if you can please cover a video on how I can understand it better it would be great gob bless💯👍

This was easy. I've not learned algebra but simple maths is easy thanks to learning the times tables in primary school! I'm now 70.

Do you provide tangible ( paper back, hard cover) for your courses or they all digital. I like to learn from books - senior citizen here.

18÷3=6
6 • 2=12
12+4=16
16 is the answer

[fryque]

One of the easiest to do. Very straightforward. However - there is NO reason that you could not use parenthesis.

[terry_willis]

OK, I got 16, the correct answer, but I did use my HP calculator.

[nfpnone]

So, 18 * 2 = 36, 36/3 = 12, 12 + 4 = 16

Sorry, I didn’t use PEMDAS, and I didn’t work the problem left to right. Why did I get the right answer?

[thomasharding]

And again, the answer is YES! And for those who thought he wants the value of the expression, it's 16.

[kevingood]

The answer is 7. You multiply first, then divide then add. We were taught BODMAS, which means, By, Of, Divide, Add, Subtract.

[KW-gbcd]

I got 16. It went like this: 18 · 1/3 · 2 = 6 · 2 = 12, 12 + 4 = 16.
