Hi, we're Kelly and Steven!
Welcome to mathically, where we basically do math! I've always struggled with math as a child, so I love helping my students really understand it by explaining it in a way that makes sense to them!

Thank you. I remember there being a hidden rule just didn’t remember
W’bout BODMAS? Edit: BODMAS = Brackets, Order, Division, Multiplication, Addition and Subtraction
Her tutorial is wrong, the correct answer is 1 Because there is no sign of multiplication in the given. in pemdas rule, The parenthesis is also a multiplication even without a sign of multiplication but you can't change or replace it in multiplication sign. if you want to know how the answer became 1, here's the correct solution below. 16÷4(3+1) 16÷4(4) 16÷16 =1 If you confused, you can try it to solve in scientific calculator.
Thank you.
Thank you!!!
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.
I was already know that the ans is going to d btw superb explanation 👏
4() is implied / juxtaposition, the true ambiguity is whether juxtaposition shares the same priority as an explicit multiplication sign.
Another example of why PEMDAS is only suitable for young children:- 2^^2^^3 PEMDAS evaluates it as 64 It's actually 256 PEMDAS is a primary school tool that breaks down with anything more advanced than very basic math.
Wrong. PEMDAS is only fit for primary school level maths. The answer is 1. Learn about the priority of juxtaposed multiplications. PEMDAS says 2a/2a = a² But 2a/2a = 1. Ask anyone who actually USES math professionally instead of just learning ridiculous rules by rote. THIS is the video you should be watching kzread.info/dash/bejne/noB3psWaZse_oKQ.html
16÷4(3+1)=? 16+4(4) 16÷16=0
That would be 1
Juxtaposition is needed
I didn't understand nothing she said your saying too fast
My math grade has gone up so much bc of you tysm
Thanks bc my teacher explain it a way that I don’t understand but u helped me because my New York State test is tomorrow wish me luck 🍀
That’s why I never liked math 🧮, back in my days, The (3+1 ) would have been multiplied by 4 to 16 , then 16 divided by 16= 1 , we followed by the letters PEMDAS , there was no left to right rule
PEMDAS PEMDAS OHHHHH
Can you please do a part two of PEMDAS
1/9 < 1/4 Because 1/4 it’s a quarter of 100% which would make it 25% and for the 1/9 idk how to explain but it would be 11.11% of 100%
You have to distribute the 4 across (3+1) 🤦🏾♂️🤦🏾♂️🤦🏾♂️. The answer is 1. PEMDAS is convention. Distribution is a mathematical law. 16÷4(3+1) = 16÷(4(4+1) = 16÷(4×4) = 1
Thank sow much
12 cups thank you so much I needed this for my first year of science AASA!
or boadmas
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.)
No it's not. Learn about juxtaposed multiplication. The answer is 1.

> ...,though you could argue that once the brackets are worked out you lose the brackets No you don't. Once the INSIDE of the brackets are worked out, you're left with 4(4). There are STILL brackets, so they get worked out next to leave 16. Only THEN do you do multiply & divide.
This is actually so helpful
Just got a new sub
you write how you doing
is not pemdas is bodmas😊
Its the same thing
left to right and the multiplication is first before the division why did you start division before multiplication?
1/4
Thank you. Never taught this.
Why do I remember an alternate rule where you have to multiply the number in front of the parenthesis then? Seriously, Idk why I’m thinking that. Eg. In this example, 4x3 and 4x1, then add?
E means Exponents if you’re new to pemdas
Where did you buy that pen😅😅
But why did you use addition first? It's second to the last, before Subtraction, i didn't get the logic for this one, since you mentioned earlier that pemdas is the proper ORDER we need to follow but you didn't follow it really.
It's in parentheses
PEMDAS rule doesn't really makes sense since you didn't really follow it. I dunno why people created this shtty rule
Does it only work for 9?
Thank you very much😊
Thank you for your content. 😊
Perfect for my exam! Thank you so much.
Tysm THIS HELPS ALOT OMG (pin pls? +EARLY!)
Thank you so much now am not stressing no more 😊😃
Still don’t make sense shouldn’t divide go first since it’s first on (pemdas) or do you go from left to right what’s on the problem
Nice 🎉
Finally a video that just gave me the explanation without nonsense haha
Lmaoooo😂😂😂😂😂
Unfortunately, the explanation is 100% wrong.
@@peterthomas5792 it really isn't wrong. I used this method in a question in my coding course. You have to know about pemdas for coding. The result was correct because I followed this explanation.
@@Islam-and-boxing Coding knows nothing about juxtaposed multiplication or stacked exponentiation, so coding will never teach you why PEMDAS is wrong. Try doing a maths course taught by someone who actually USES maths professionally such as, well, a mathematician, physicist or engineer.
@@peterthomas5792 Well you've made a claim... Can you now provide the evidence of how it's 100% wrong?
RECIPROCAL (i think)
We have bodmas bruh
I’m in 3rd. Grade and I know this
Can you plezz make a one video for me about the math begner to advaced❤❤
I like she uses 2 digits number when in real life u use three or more
