Incredible!
The way you teach with such calm and pay attention to details is just fantastic and worth emulating.
Kudos!!
This really helped in my preparation for WASSCE. Thanks so much
You're welcome, Ifeoluwa

Thank you very much
Bravo!
God bless you sir
Infact u are the best
Thank you so much it was so helpful Sir
God bless you sir
Glad it helped
Thanks sir
I don't understand when you u were marking the point for -x
I love it,it really helped me,I made my A
Weldon sir!
Pleased sir, I need more clarity concerning the meaning and how to apply this “2cm to 1 unit or any other units." I don't really understand that part very well.
I want to really know how it works so that I won't make mistakes when I am writing my Exams 🙏🏻.

All the best
Hi...
With great pleasure
What if there are 10 boxes in the graph?
You can see that scenario in this more recent video here...th-cam.com/video/iL3bZ-ndU_4/w-d-xo.html
All the best
Thank you very much very helpful but your videos are not clear enough pls improve on that sir, you're doing a great work here God bless you.
Dear Chuks, you should check the resolution with which you view the videos. Most likely, your device defaulted to a lower resolution. Set it to at least 720p and you'll see the difference
Sir what's DIY
Do it Yoursef
Please how is 0-x =-x I don’t get it
Take -ve sign as you being a debtor to a bank. So, if you owe a thousand dollars, that's -1000.
Now if you owe an insurance company nothing, that means you owe them 0 dollars.
So, your total debt is 0-1000 which is still -1000 dollars.
By the way, you can simplify stuffs by taking debts as negative numbers.
Hope you get the gist
But since 1_x is not possible how is 0_x possible
@@tosinnathaniel8269
Well... If I'm to answer this
The reason why 0 - x is possible, and not compared to 1 - x will be because 0 could still mean 0x. So... We have:
0x - 1x
= (0 - 1)x
= -1x
= - x
My own explanation though...
@@cresttutor2353 am still not convinced,maybe it's because of what I have been taught, that is why am confused.
But 0 doesn't mean 0x....I disagree with that, x means 1 only when you are adding it with a number with d constant x
D scale you used can be confusing to youngsters,,, from box to box is 1cm,,, applying 2cm box to box,,, is not ideal......
You can subscribe and watch our upcoming videos to catch the ideal scale as requested. Thank you for the feedback
