She aged 10 years waiting for him to get to the point! GET TO THE POINT!
At 4 minutes in I derived that this guy is the kind of teacher that turns kids off to math. HE NEVER SHUTS UP AND GETS TO THE POINT…!!!!
I really like your math videos but please cut down on the babble! You didn't even start looking at the problem until more than 5 min. in !
How to make math really boring.
I mean no offense, and I love your content, but why is it that when every video has feedback about it being long winded, subsequent videos seem even more long winded? Math is tedious enough for most people to learn.
Nothing but gab for over 5 minutes, folks. Fast forward.
She's 15 and he's 7. Next year, she'll be 16 and he'll be 8. I'm not a math genius, but I can figure that out in my head
Way too much talk. Get to it. I don’t have all day!
Thank you for reminding me why I dropped out of highschool. Teachers always tested patience by talking too much!
Took under 10 seconds not 21 minutes. He is 7 she is 15 next year becomes 8 and 16. Speed it up !
I am a retired mechanical engineer and quantum physicist with a PhD in both fields. I was a research scientist in both the space and arms development fields. Mathematics were my entire life. However, four years ago I suffered a stroke. Now my mathematical abilities are no longer there. I struggle with the basic concepts. Even many of my writing abilities are much less than they were.
I would have solved for the age Beth would be next year. And, since we know Beth would be twice her brother's age next year, we can simply take the eight year difference and multiply that by two to get 16. Then, just subtract one to get Beth = 15 years old right now.
1. Please get to the point. 2. Give students a massive tip: You read the call of the question line first. I.E. "How old is Beth now?" OMG! Beth will be eight years older than her brother next year as well as this year. x+8=2x. Solve for X. X=8. Next year B and B will be 16, and 8. Subtract one for this year: Beth is 15. Brother is 7. For heaven's sake.
The reasons students get distracted is because the teachers spend too much time rambling on about non-essential information not relevant to the equation. I had a teacher like that. He would spend 30-45 minutes talking about how to solve a different equation, or what a variable i, etc. He then would rattle off a new equation for 5 minutes and then turn the class loose with the assignment as homework. Always wanted to see the work for each equation. The only people that liked math were the ones that could solve the problem in their head, and just wrote down the equation as they went. I was glad when the semester ended. I hated Algebra, still do. My life goals didn't include a job at NASA, JPL, or anywhere in the scientific field.
I am a retired computer programmer and I set up two equations: 1: x = y - 8 and 2: y + 1 = 2(x+1). Substituting the 1st y - 8 into the second for x allows you, after moving things around, to solve directly for y. I just wanted to see if I could still do it at age 71+.
no wonder I was always useless at algebra. I have never watched such a long winded video in my life! I had the answer of 15 in about 15 seconds just reading the problem but never would I have sorted out all your working out. I have a block on finding the easy way to do anything, always have but with algebra would read problem and solve in 30 seconds but could never understand the reason for the long working out of it. Drove my maths teacher crazy and my physics teacher would laugh and say my brain was weird because I always knew the answer without having to sit and work it out. I get where you are coming from but I don't see the point of all those workings out for nothing.
My daughter, at age 16, asked me for help with math.
I did it in my head in 2 seconds. Next year she'll be double her brother's age, so Beth is 15 and her brother is 7. However, I can see where the algebra would be needed if the question were more complex. Good video!
Really starts at about
For every exam I took throughout my undergrad degree work in mathematics, I started each by writing across the top page of my answer, in large capital letters RTFQ. It was a great reminder.
