@@mathically You are INCORRECT with your "invisible times". __ONLY__ the USA teaches this nonsense in middle/high school. If you ever take math (e.g. physics or engineering) in college/university you'll fail. 16 / 4 ( 3 + 1 ) = 16 / 4 ( 4 ) = 16 / (4 * 4 ) .... aka distributive property... it's math. If a rule applies in one location, it applies everywhere. = 16 / ( 16 ) = 1. Your mistake and it's SAME with ALL U.S. HIGH school teachers ... is inserting a magical multiplication sign. 16 / 4 ( 3 + 1 ) DOES NOT EQUAL 16 / 4 * ( 3 + 1 ) Ask any human (who is suitably trained in math) what does 2x/2x result in? The answer is 1. However with your logic (and the same for Google) the answer is x^2. This is 100% wrong. Similarly try evaluating 3^2x ... that's not 9x ... that's 3^(2x) ... since we don't know what x is ... the expression is already in its simplest form. All of this is explained under JUXTAPOSITION. PLEASE STOP TEACHING PEMDAS. PEMDAS IS ***WRONG*** (unless you're just teaching elementary school math).

​@macbain1395 PEMDAS doesn't break any rules of algebra, the interpretation people lay on expressions DO, however. In addition with the obelus, which is not a vinculum, is basically a fraction with a numerator on the left side and on the right side. Writing in text has a difference between writing in paper, which often uses a vinculum rather than an ambiguous obelus or solidus. The simple PEMDAS interpretation of the expression 16/4(3 + 1) is not breaking any rules of algebra whatsoever, since if we break 16/4 down to its multiplicative inverse, we find that we have that as the coefficient of the term (3 + 1), THEN distribute within the parentheses. That's where you went wrong on the distributive property, the coefficient of (3 + 1) is not 4, but it is 16(4^(-1)) juxtaposition is still in application regardless, you have to remember that without the parentheses to group the entire denominator, say: a/bc, as per the interpretation of a solidus, not a vinculum it goes: a/bc = (a/b)c = ac/b Algebra does not fall apart in the midst of PEMDAS, it's the overcomplication and the misunderstanding of simple mathematical perspective on the given.

BODMAS/PEMDAS isn't the issue here. It's how the 4(3+1) is treated. It's arguably ambiguous (though you could argue that once the brackets are worked out you lose the brackets so are left with 44 or 4×4. Treating it as 44 is daft so we are left with 4×4 and then 12÷4×4 is clearly 16.)

4() is implied / juxtaposition, the true ambiguity is whether juxtaposition shares the same priority as an explicit multiplication sign.

16/4(3+1) 16/4(4) This can be interpreted two different ways a/bc or a/b x c which basically 16/(4(4)) vs 16/4 x 4

Perhaps you'd all be better off asking ChatGPT instead of some random KZreadr:- a) What is 16 ÷ 4(3 + 1) ChatGPT To solve the expression 16 ÷ 4(3 + 1), you need to follow the order of operations, which is often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). So, first, you should solve what's inside the parentheses: 3 + 1 = 4 Then, you multiply: 4(4) = 16 Finally, you divide: 16 ÷ 16 = 1 So, 16 ÷ 4(3 + 1) equals 1. ------------------------------------------------------------------------------------- Conversely:- What is 16 ÷ 4 x (3 + 1) ChatGPT To correctly solve the expression 16 ÷ 4 x (3 + 1), we follow the order of operations: Parentheses: Evaluate what's inside the parentheses. Multiplication and Division (from left to right). Addition and Subtraction (from left to right). So: Inside the parentheses, we have 3 + 1 = 4. Now, we perform the multiplication and division from left to right. We first divide 16 by 4: 16 ÷ 4 = 4 Now, we multiply the result by 4: 4 x 4 = 16 So, the result of the expression 16 ÷ 4 x (3 + 1) is 16. ------------------------------------------------------------------------------------- NOTE THE DIFFERENCE IN PRECEDDENCE BETWEEN EXPLICIT AND IMLICIT/JUXTAPOSED MULTIPLICATION.

im originally South African so im used to just call it B O D M A S B = Brackets First [()] O = Order of Operations [x², √xyz, etc] D = Division [÷ / ½] M = Multiplication [× / *] A = Addition [+] S = Subtraction [-]
