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

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.)

I do a little of both. My kids used to be upset when I would not let them use a calculator for homework even if their teachers said that they could. I thought that it was a stupid thing to do. How will they learn?

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

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 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, rosdimy

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!

Mentally calculating is one of those things you can only keep doing right and fast if you keep practicing it, in my opinion. That's why I try to calculate without a calculater as much as possible. For the bigger numbers I use a calculator, for taxes, etc. For watching my earnings and expenses I use a speadsheet in excell which shows me exactly what I have left end of the month. I like to use a spreadsheet for the cause because it gives me more insight into the upcoming expenses so I can calculate ahead.

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 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!

Even I don't like to use calculator while studying, but, now I grown and started a business, I do even the silly calculations with the calculator, coz, we are more thinking of business and other things, so, we automatically searching for the calculator for small calculations also....

Yes Mayka this is indeed a sad state of affairs.When we were in school we were never allowed to use the calculator with the result that we developed good skill in mental calculation of figures.But today's generation are encouraged to use the calculators at a young age(to speed up their home work),with the result that they are unable to calculate even small figutres mentally.....

I never used calculators while studying, mental math is better that calculators. When you are shopping you cannot have a calculators to find out the discount price or which one is less cost. So mental math is better than calculator.

As i am not so good in maths. I try sometime to do it mentally but sometimes i use the calculator.

I'm not also using a calculator! I have also observed but and I realized that not all of us were gifted in math! It is a skill to calculate mentally especially when it comes to big figures.

I am able to do most of the calculations mentally.I just don't like to reach for the calculator at the slightest pretext.It will definitely kill whatever little calculating power your brain has.

in our school days,we were not allowed to use a calculator but nowadays i find that as soon as kids start finish learning their numbers,they are told to use calculators which,according to me doesnot sharpen their mental faculty.the simple 1+1 question,makes the kids to hurry to get their calculators.

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.

i usually do it mentally but will double check w/my calculator especially in my checkbook.we all make mistakes but i don't want to make a mistake in my checkbook.

hello, I am just horrible in math , and for the most part I leave all things dealing with numbers up to my fiance. back in school i did use one , but there is only so much one can do . Ugg math ! take care

I usually do mental calculations, and most of the times, when I go out, I usually take my son or daughter or at times both of them, and I ask them too to calculate for them to practice their Math. It's a nice practice for the kids and me, and we do have fun doing it.. :)
