The end answer is correct but i got x=0 instead of x=3

[@jh-ow2zd]

As long as end answer is correct

[@syakirharith]

​@@jh-ow2zd phew,i tough my calculator is fake bc i get x=5 instead of x=3 but my end answer is correct

[@omorisballs]

prob you just pressed the solve button once, press it again to view the answer

[@wnnxuannn4828]

i got x=0

[@zhalosky]

Its the initial guess function. Not sure why it does this but you can set it to correct answer to make the process faster. But as long as the end result is correct its a real one

[@arciv7851]

my calculator is fake but it has the same exact answer and it instantly give the answer because most fakes takes around above 10 seconds to get the answer or it just give " cannot answer" error

[@jh-ow2zd]

Wow maybe u got a better quality fake! I just dont want to wonder when my calculator is going to be right or wrong

[@rafiqah2427]

My calculator says x=0 at first. Second attempt, x=1. And try again many times, same x=1. Is it fake or not?

[@jh-ow2zd]

Dont look at the second last step. Look at the final answer only

[@jh-ow2zd]

If u want you can try other sums like 27/x=9. Solve for x. Answer should be 3.

[@SzymekCSC]

Another way to check is asin(acos(atg(tg(cos(sin(9)))))). If you get 9,000000007, it's genuine.

Thailand Casio real or fake ? The answer all is correct 💯😊 =1

[@ammarmuhd4023]

Why i get 9/x=9 x=1? But its original

[@shah9921]

Because it's made in china

[@plcerider6502]

9/1=9 so x=1

[@zhalosky]

Its the initial guess function. Not sure why it does this but you can set it to correct answer to make the process faster. But as long as the end result is correct its a real one

[@jingmingkhew9203]

so this is the real or fake calculator？？

[@jh-ow2zd]

This is the real calculator. The fake one cannot perform this sum.
