Wishing you the very best!
Thanks. This really helped.
Thank you God will bless you

Thanks alot sir. I really appreciate this
Hello sir for the DIY answer is D = 11.00 , thanks its very helpful
Excellent Video
god bless you brudda really
Thank you so much man. I never know my calculator can do that much computing power.
Thank you ☺️
you can always count on a nigerian prince to help you with the mathematics
Thank you buddy
You're owesome..
Thanks legend
Thanks man, literally saved me! 🤟🏻✨
Glad to know about our "mission accomplished"
Thank you so much for the video is very important, but can someone solve mode Lowe question with calculator

What of if you have two variables
thanks
Pls, where and how can I get this calculator?
God bless you abodancely
Please the second one is showing syntax error for mine. Urgent
Please where can I get some of your calculator to buy please
THANK U
UWC
My maths teacher always doesn't want us to learn other use of the calculator and prevents us from using Casio calculator in exams😂
Karim, it's good to understand and be competent in solving the questions on your own. The calculator is just a tool. What you know, you know you know!
How can I say thank you 1000000000000 times
Love from Lahore Pakistan
Wooow. Thanks a bunch. Global village connect from Lagos, Nigeria
How to find value of f:(1/f^0.5)_2log(f^0.5)-8.558=0
Thanks for the tip. God bless you.
But my calculator didn't solve the second equation.
Ameeeen.
Did you remember to clear the memory of your calculator? What about your initial iteration value? Check again to master your calculator. The second question and the assignment are the easiest.
Glad you are trying it out yourself. Keep up the good work. 👍
@@DavetutsAcademy Thanks. I'll try clearing the memory but I don't know how to change the initial iteration value.
For the second question, zero (0) will do as the initial value. Try watching to the end again to see the example with two values as the solution which warrants different initial values for the iteration
@@DavetutsAcademy Okay boss. Thanks again for all you do. You deserve more recognition.
I try solving but my calculator is showing me syntax error
Does this work on ti 84 plus ce?
Just try it out. Don't know if it can or can't. Check the function of its available on the calculator
sir my calculator (fx-991ES PLUS) cannot work on this tips
it gives error
M y qustion is this ( LOG base 8 (X)+LOG base 8 (X-12)=2 ?
sir first Q of yours vedio was solved in my calculator but mine Q alls cannot solve on this tricks
Make sure you reset your calculator before use with the right mode in use. Also note the initial value of your calculation. That should take care of the question as appropriate
Sir i rest my calculator always after solve any Q but it cannot work
Sir how to calculate 2.5 log base 10 2.5-1.2
And what if I didn't know the normal calculation how will I get the second value
When I put x=0 answer didn't came
shift 9 3 = data all clear???
Yeah!
Please can you explain why selecting the value of 35 on other number to get the second value of m (which is equal to 32)
You want to pick a number greater than the largest value and another number less than the least value. That's the idea behind it. Hope it's clarified.
@@DavetutsAcademy Thanks for clarification
Hi, I need someone to help used a calculator

Casio fx 82es has no calc button
It's a lower model. The 991 series and above features that, including the 570 series
My calculator is saying syntax error🤦♀️
My calculator can't solve pls
11
Why didn't you add 10 as base in the 2nd question?
That was explained at 7:33
Base 10 is the default base so you may choose to omit it because inherently, that's where we are working from.
Hope it's cleared
@@DavetutsAcademy o thank you so much. How can we tell whether a base is the default or not?
Base 10 is the only default base. Si you may choose to indicate it or not as you wish.
However, you have to indicate any other base you are working with.
Hope you get it right
@@DavetutsAcademy ok sir, understood. Thank you so so much 🙌
My calculator can’t solve it pls why?
You need to have the right calc spec. This is Casio FX991ES by the way
in last one why did u put 35 and how u got 35 why not 40 ??
You can use 40. I chose a number greater than the "32" which I was expecting. It's my personal style and you can develop yours too once you've mastered the use of the calculator.
@@DavetutsAcademy u expected that it will be greater than 32 that is mean u could put 32
@@amoali8014 I have calculated the second answer to be "32" as shown on the board. SO I want a number greater than "32" to use as my initial value.
You will find this process useful when the answers are close, say 3 and 4. In that case, I can use 0 and 10 as my two initial values. 0 is less than 3 and 10 is greater than 4.
the best african in all time
Sigh my calcutor is the older version
Sir make video in hindi
He is Nigerian 😂
Alas, I have no clue to hindi!
Apologies, please
ً
Speechless?
👍
You should make it in English language
It is in English language
i am trying but you are moving soo fast
In the video setting, you can change the speed to a more convenient space. Do try that out
plz speak clearly
Sounds like a Nigerian accent 🤔
Yes oooo. Naija blood all through
I didn't understand at all what he said
Thanks for checking out the video in the first place. You can watch in higher resolution and Audi out on the subtitles so that you can follow along. Hope you'll find our videos resourceful in building your academic excellence.
