woonhowhin because sometimes x can have many answers at the number line , so u will need to tell the calculator u wan the one nearer to 100
And can i use x=100 for all questions?
Almost
6:05 sir, i put this whole equation in this calculator, and its loading nearly 10seconds, after that it show "cannot solve". Why sir?
_I'm panic_ 😰😰
Are u typing the same with mine ? And are u buying the genuine calculator?
Sir why do we need to let x=100?

Just double checking, this calculator is allowed in IGCSE add math rite
daren kaulsay so far my students all use this calculator in IGCSE and got no problem . Maybe u should double confirm with your school teacher

Why did u type x= 100 at 3:35 ??
Because when u solve it , you might has more than one x answer , this is how the calculator know where is your x value

hello sir, why we need to click 100
To find the answer at that range
why we need to use 100 at last of the answer?
to indicate the value is at positive zone. u can use 10 or 50 or any other positive numbers
