my years of math set me up for life. it ordered my mind, made me read and write critically and assisted big time in any other field of study. helped me with a coupla promotions at work, helped me mentor my kids with their studies. helped me read people. I remember a teacher once saying that the Greek meaning of the word "mathematics" translates to "The study"
Nice Vid.
Time start for the introduction is 7:38
did not peek, but took 20 minutes to get the answer. I am rusty. was a top student 35 years back. got as far as finishing the 2nd course of a 3 course college calculus sequence. ain't no rocket scientist but I am persistent. always liked the challenge. enjoy the vids
Now there's a refreshingly positive reply.
Outstanding, great teaching!
You deserved one more subscriber, great work!
New subscriber here. This sort of question appears quite often but I cannot fathom this one out. (Harry works in a cafe where an 8oz coffee cost £1.40, 12oz costs £1.80 and a 16oz £2.15. In the day he sells 800oz of coffee for a total sale of £121.65. How many 12oz coffees did he serve?) can you shed any light on this problem? Many thanks.
Wow...11 minutes to get to the meat of the problem. No wonder people tune out.
hey... the guy provides this FOR FREE so he has to "run his.commercial." There's a slider at the bottom for us who know his thing by heart ao we can skip the intro...
@@tomtke7351 Exactly!
@@cbesthelper404 The man gives us so much wizdom... trudging thru a bit of him selling his product is no problem... besides, you can easily jump thru this by the slider... so what's your problem?
@@tomtke7351 I know. It's free. If someone wants to "fast-forward" through, they can easily do so. All the complaining is quite unnecessary. I appreciated your comment.
Yep, prattles on too much.
whatever you divide the numerator by so shall you divide the denominator.
y^2+y/6y-3 not if it's correct
top (2 y^2)(3 y^2 + y - 2) ...... (2 y^2)(y + 1)(3 y - 2)
bottom (6 y)(6 y^2 - 7 y + 2) ..... (6 y)(3 y - 2)(2 y - 1)
so ..... [y(y+1)] / [3(2 y- 1)] ..... i would still like a top down scribble page lol
Solve this for me: A two digit number is such that when the digits are reversed the value of the number increases by 9. Three times the sum of its digits is less by 8. Find the number.
Hey, I’m curious. I’ll use chat gpt to find the answer. Hope you don’t mind.
Is that a riddle or actual math? (In the sense that you’ll be able to compute your way into the answer)
How dare you spend all that time advertising and don’t have time to show us how you factored the problem because “it takes too long.” Where I got to go?! Where you going?!
math teachers ALWAYS say “you should already know how to do that” thats why I hate math now.
Literally my thought process
The reason they say that is that Math builds, one concept on top of one already mastered. So, a teacher cannot go all the way back to the beginning each and every time. Once you reach the level of Algebra, it is assumed that you know Pre-Algebra. In this case, this is a rational expression which is introduced to students AFTER the students have studied factoring. So the instructor is focusing on the new topic and is rightfully assuming that the student already knows the earlier topic of factoring. If the student DOESN'T already know it, then whose fault is that? It's the student's responsibility to keep up with the lessons. It wouldn't be fair for the teacher to continue to backtrack when other students are ready to move on.
This instructor has created a lot of videos of factoring. That is why he is moving on. You can always go and view his videos on factoring, and then return to this one for greater understanding.
