Do you use a calculator or do you mentally calculate??

i am not great intelligent in Maths.
But i never use calculator for doing simple calculations & also for other counting purposes which are in 100's..
but if i need to count plenty of 1000's, then i usually go to Start --> run --> calc --> enter
and start doing my calculations in system itself..
Actually, I totally forgot about the real calculator nowadays as i always use mobile and system calculator.
But a Good invention..
& nice days those are.. when i was used to spend plenty of hours in calculator, checking whether the calculator is giving the right answer, in my childhood days!

I try as much as possible using mental calculations or pen and paper rather than using the calculator. I believe in keeping the mind active because the brain can lose its ability if not much stimulus is given to it. I have seen youngsters unable to perform simple calculations without reaching for the calculator. I do not want the same thing to happen to me.

all the best,

I mentally calculate. In school we were not allowed to have calculators, unlike students that are actually suppose to have them in certain grades now. I can calculate it in my head quicker than on a calculator. So I don't have much use for one. About the only time I may use one is when I have a whole string of numbers to add like 30 or forty. But most times I don't use one for this either. I guess I might be weird and not like others that may mostly use them. lol

I can do mental math for easy MDAS, but there are cases that I will really need a calculator like when I deal with scientific notations, logarithms, trigonometric problems and any computation that needs a scientific calculator. I always bring it with me specially in class.

Good day!

i also calculate mentally like you do.a tip for all suppose you have to multiply any number by 11.

example:53 x 11

5 _ 3 (add 5 and 3,and put 8 in the blank space.the answer is 581).

example:58 x 11

5 - 8 (add 5 and 8,the total comes 13,put 3 in the blank space and carry over 1 and add to 5,the answer is 638.)

Most of the time I will calculate figures mentally. It all comes down to the complexity of the equation though and I will also use the calculator on my phone to double check my mental figures sometimes. When I was in school, we weren't even allowed to use them most of the time! It was only in my later years that they were introduced but I didn't study the math areas that allowed them.

i will calculate mentally,as i am pretty good at maths(dont think that i am raising my own chair)as you said,my maths teacher will shout at me if i use a calculator,and so i love to calculate mentally..so this is about me and hope we both have same kind of method!these are friends and thanks for starting a nice discussion,bye!!

We didn't have calculators when I was in school back in the stone age.



If I'm doing something simple, I won't use one, but for most things I will. If I write a check I'll usually just do it in my head for the one entry, but if I have several entries to catch up on, I always use the calculator. Either way, I always check it every few days online and have the calculator handy while doing that.

I tend to do it all in my head, whether it's sales tax, tip, discounts, whatever. It's just faster for me. I don't even use a calculator if there's too much to calculate in my head - I'll write it down. I have used a calculator to see if I'm right, if I'm not sure, but mainly I just rely on knowing math.

While back i school days was different Mayka but now I find myself confused with numbers and I use a calculator. I do it mentally while counting small figures but a little bigger ones, I can not manage. Call me dumb, I will admit most graciously.
