There are comments saying your explanation is a nightmare, or over-explaining, or complicating the process; however, these are people who already know how to do the math. Your videos are for people who DON’T know the math. I find them helpful and fast forward past information I’ve learned already from previous videos. Thanks for putting these out. I’ve learned a lot.

both subtraction problems in parenthesis first, then multiply those two, then subtract the -1.. 4-6=-2 and 6-4=2 -2x2=-4 -4-1=-5.. the answer is -5.. or C!!

Your channel is brilliant! I learn so much here, cheers.

I love the way U explained how the M.D. is a grp and to do ÷ first if it comes first. I never knew that.

I have always loved math. Thank you for your channel & method review!

Why go the long way around a simple problem!?

I was always screwed up on show your work. Some teachers wouldn’t give you credit without it. I love that this was multiple choice.

Thank You for doing this Math Courses, I'm so grateful because everything I knew about algebra I have mostly forgotten. I do remember the order of operations rule from long ago thanks to you. LoL Thanks for helping me shake off the cobwebs. You're an amazing teacher.😊

I have always loved math, but even I still struggle with it during my current age in life. And I really enjoy the refreshments of reviewing mathematical equations and other things. Thank you so much, Mr. Zimmerman

I had this math going to vocational college. I had a math teacher who help me out a lot with math.

Your explanation of this problem is a nightmare. Just my opinion 6-4 = 2, 4-6= -2, 2*-2= -4, -4-1=-5, easy

Agreed; this explanation seemed scattered and excessive. These videos are usually more succinct. State the proper order and correct result first, then get into the explanation and any necessary discussion of where folks may have gone wrong for those who might need it. Nearly 23 minutes requires more attention than most students would have to give (just like my comment! 😜). But I truly do appreciate these math refreshers. Thank you!

When I was in high school (60 years ago), we always had parenthesis and exponents. I never had any problem then, but without parenthesis and exponents, your PEMDAS explanations definitely helped me since.

Love these little challenges!!

Thank you,Mr.John.

Thank you Mr. John!

When I was young this was simple but somewhere along the way they changed the rules. Simply stated, math is very precise so expressions need to be precise. Instead of P.E.M.D.A.S it should be (P).(E).(M.D).(A.S) or something similar to clarify order of operation.

I love the videos. They take me back many years ago 😅 but agree with those that ask for more simplicity. They would be more enjoyable and easier to understand if you go straight to the point: order of operations and then solve it 👍🏼

I am a literary type but when I follow your problems my mind clears up and I feel a lot of satisfaction. Has anyone measured the brain waves of people listening to a favorite symphony or watching one of your math lessons :)? it would be interesting to see how the synchrony of different parts of the brain gain coherence with different types of experiences.

I used to be a solely literary and art person, but since learning maths I have come to appreciate the perfection of maths, and how calming it is when you understand it.

Wow I learned so much from this one Thank You

The problem with basic math is that everyone forgets the rules that you learn from elementary and secondary,for which I believe should be added to every test and it's not cheating,some people have photographic memories while others learn by repeating. Order of operation is forgotten for some,just a suggestion to either right it on the chalkboard or on the test paper

I'd like to XPress My Answer is -5. :) Technically, there is no such thing as subtraction, only addition of a negative number. And division is but the multiplication of the reciprocal value you are dividing by. Also, back in my day, if someone handed you an equation like 5*4 / 3+1-2, you would hand them it back and tell them to format it correctly.

22m for something that can be explained in about 1or2m. CRAZY!

This maybe why school children are having a difficult time learning math. KIST keep it simple teacher... Smart guy certainly a fine instructor but could help my Grand - kids do High School math the way "modern" text books are written. Maybe grade school math instruction isn't up to par but last few years average math test results are heading down.

Love the knowledge

If you insert an = at the end of the equation, the answer would be -5.

Good math Solutions. Subscribed.

Thank you 😊

My math skills from grade school and high school helped me get this right. I am not even someone who likes math generally 😊

Do brackets first, followed by multiplication and division and finally addition and subtraction- so (4-6) (6-4) - 1 = (-2) (2) -1= -4-1=-5

Nicely explained ,but 22+ minutes for what took me 10 seconds to solve? 😅

Brackets mean multiply. (4-6) represents scale e.g. - 7 -6 -5 -4 -3 -2 -1, 0 + 1, +2 + 3, +4, +5, +6...... So + 4 -6, count backwards = -2 -2 x (6-4) = -4 -4 -1 = -5

It just took him 22 minutes to explain something you can do in your head in 10 seconds.

That was helpful I’ll remember that next time.

BEDMAS Brackets, Exponents, Division/or Multiplication, Addition/Subtraction

this is a really good lesson. I forgot some of how negative numbers work. So thanks :)

You lean this in basic math or Pre-Algebra It a lot of schools it is a requirement to pass Algebra 2. To graduate from High School This is a state requirement.

TWENTY MINUTES ! Just to get to the point of solving the actual math problem. 🥱😴

B. After watching how to solve this, I got it wrong. Its just not logical ... I thought math is supposed to be logical!

Yay! Got it!

c) -5

I liked it thank you

Thought I must have got this wrong because it was obvious. Thought must be a trick and expecting to be told so . But NO so happy I got it right but sad I didn't learn anything 😇

-5, that is my answer, probably wrong. -2 x +2 -1...- x + is a minus so -4 then -1 =-5.

Once again. the implied multiplication is going to screw things up.

That wasn't the way I was taught. (4-6)(6-4)= 4(6-4) - 6(6-4) = 8 - 12 and the extra -1 = -5. That thing where you changed all the signs yuck.

At the title card, PEMDAS returns! My answer is c) -5.

Does anyone remember & still use, number lines?

Yes, but there are no brackets in this problem. There are parenthesis, which are different from brackets in the rules of math.

A -3 had it right then second guessed

(4-6)(6-4)-1=? (-2)(2)-1=? -4-1=-5 It is simple equation it doesn't require much explanation as you told

Very intresting channel.

Went with 3, wasn't sure if x by a negative made it a positive .

Totally besides the intent of the vid, you went into dollars examples. I think a lesson on compound interest, for assets vs. debt would be nice. Would still be plain high school math.

WOW!..... WOW! 😮 Wooo👍

Both are valid methods. They both work.

I’m going to make a suggestion: after going through the process of solving a problem end these tutorials by presenting a practice problem with four choices and a key code. Set up a web page that only has key codes and the corresponding correct answer (from the aforementioned multiple choices). One page should easily handle 16 or 60 lines of keycodes, times four if you put them into columns too. Maintaining one page shouldn’t be that onerous and as a teacher I needn’t tell you the value of practicing the same skills just taught. Anyway, as I said, a suggestion.

That’s what I couldn’t remember ++ and - -. Now I know.

A negative times a number is always a negative

In the 70s , we never heard of PEMDAS and just did our algebraic equations left to right anyway. How long has this been around John?

Multiplication having higher precedence than addition has been the way mathematical notation works for a few centuries now. Acronyms like PEMDAS seem to have been around for 100 years ish, maybe a bit longer. Actually teaching these rules in the context of simple arithmetic was more patchy in the past than it is now though. Some people who learned in the 70s or earlier were taught this, but certainly not everybody. It doesn't really matter for this question though, because reading it left to right gets the correct answer anyway.

-5 P, (4-6) × (6-4) - 1 Multiply, (-2 × 2) Subtract - 1 change to add and negative sign is still remained , -4 & - 1 are added = c-5 It can be also -3 because it is minused positive 1 outside the parentheses.😂
