Doing math in your head

Doing math in your head isn’t always easy. Sometimes when you do math in your head you stump yourself because you can’t mentally figure out what you’re doing. When we are told to find out the answer to a problem in class mentally all of us always have blank stares in the beginning because we aren’t used to doing math in our head. When I have to do math mentally I always want to take out my calculator to do it because it is so much faster. Some people really have a lot of trouble doing math in their heads because it isn’t always that easy. A lot of teenagers hate doing any type of math in their head because every teenager grew up knowing they had the technology of a calculator to do any math they needed to do.  When I’m in math class and I have a question that requires a lot of math I always have the tendency to pull out my phone to go on my calculator and do all the math I don’t want to do in my head. I feel like if teenagers now a day didn’t have the technology we have today we would not be the same. I feel like a lot of teenagers would be a lot smarter because they would be forced to things in their head or on paper. I think having the chance to show your work you should do everything you can to show all the work you need to get the full credit of whatever the question may be. When it comes to hard math that requires a calculator than I understand why you need to use one. Some teenagers use calculators to do the simplest math. I’m one of those teenagers and I can admit it. When it comes to math that uses negatives I always want to use my calculator because I never remember how to figure out negatives in my head besides when you have to negatives next to each other it turns into a positive but that’s just common sense. Calculators have definitely been a big advantage to everybody in the world today because it saves us from doing any kind of math in our head. I personally hate doing any kind of math in my head. For the simplest math I even use my fingers. Like when I have to add or subtract simple numbers I always use my hands. If I have a calculator next to me I will even do simple math on my calculator. I feel like a lot of people have become lazy to doing any kind of math in our heads and that’s all due to the advanced technology we have now a day. Still to this day when it comes to doing easy math I will always use my fingers and people always laugh at me but it doesn’t bother me because it helps me get the right answer without having to do it in my head.

  1. Could you at least appreciate that we didn't use calculators in our class? Can you see why a teacher should not rely on anything else to help them do the math except their brain? These are things I tried to make as underlying goals for the class...
