How to avoid making "careless" mistakes in math?
There are a few things I try to do to avoid errors: 1) Always keep any units riding along with the values. (3 mm instead of just 3). This way if you need the answer in meters, you'll see that you need to convert from mm at the end. 2) Make sure to use variables you won't confuse with numbers when reading them. 3) Check your answers where you can. This doesn't mean doing the problem all over again, but more sanity checking that if you plug your answer back in to the original problem that it makes sense. 4) If you have time to work the test even 1 1/2 times, perhaps you are going too fast. Slow down just a beat and make sure you haven't added 6 and 7 and gotten 15 somehow. =)
How do I stop making careless mistakes in math? Every other class is a breeze, but math kills me.
Let’s start by making a few hypothesis to answer your question:If you do great in every class, but you have a lot of problems in Maths, then it mean s probably that you have some kind of disadvantage in tackling Maths problems.You either have some false beliefs that “Math is useless” or “Math is more difficult than any other course” (for example) which unconsciously play against you when you try to learn Maths (what you think influences what you do so if you think Maths is more difficult, it BECOMES more difficult)Other possibly:You lack some understanding about some basic math principles on which everything else relies.For example, you had a bad math teacher when you were young and you never understood the part about “fractions”. If you don’t know fractions, every else becomes more difficult.Our knowledge of everything relies on the knowledge we learned in previous classes in the past, but it doesn't mean that because you did wrong in the past that it will define your future.Remember just one thing: You can always understand your mistakes and improve in Maths as in any other class or domain.Here are a few actionable things you can do:1- Try to change Math is something easy in your mind, you will learn faster(Repeat to yourself “Math is easy” and every time someone ask you about a Math problem, tell them “Math is easy”. After some time, you will start to believe it)2- Every time you find something you don’t understand clearly, make some research, read wikipedia, do some quick exercises, ask your professor, until what you didn’t understand becomes crystal clear in your mind. Then try to teach it to someone else to be sure you understand it (that’s called the Feynman technique)You can remedy to any problem by asking yourself the right questions and seeking an answer. Here’s an article I wrote some time ago, which explains how:Get everything you want by asking the right questions - Technical Sales SystemHope this answer helps you to become awesome in Maths!

How can I avoid making stupid mistakes on math tests?
I'm a good high-school student, and I've gotten straight A's on my report cards for a long time. But recently, I've not been doing so well in math class. My latest test scores were only 93 and 90 (which are bad for me) solely because of stupid mistakes, and I just got a B- on a quiz. My math grade is in jeopardy, and I really want an A in that class! I didn't make stupid mistakes first semester on my math tests, so I really don't know what's wrong with me lately. Do you have any advice on how I can stop worrying and start avoiding elementary, mental mistakes on quizzes and tests?
I know this is very simple but I keep making a mistake somewhere and I don't know where :/ help me -maths prob?
Three terms -- take the two differences and equate them: 2p - (12 - p) = 4p - 5 - 2p 3p - 12 = 2p - 5 p = 7 Check it: 12-p, 2p, 4p-5 = 5, 14, 23 Differences are: +9, +9 Check! EDIT: You say you got p = -7. It's +7; check by substituting p back into the original terms. If you use p = -7, you get 19, -14, -33, which suggests that you erroneously equated a[2] - a[1] = a[3] This would result in p = -7, but this isn't how an arithmetic sequence goes. It should be a[2] - a[1] = a[3] - a[2] which will give p = 7 EDIT2: Another possible approach is to note that in any 3 consecutive terms of an arithmetic sequence, the middle one = the average of the other 2, which means that twice the middle one = the sum of the other 2; that is, 2*a[2] = a[1] + a[3]
I keep making careless mistakes at work!?
I don't understand what is going on with me, but I have been making some very careless mistakes at work. It's already bad enough that I got off to a bad start with this company, and I am sure they have already labeled me as the "airhead". It could be something as simple as an email where I would address the sender by the wrong name or attach the wrong document. I am in a professional position so there are no excuses for this. Its like I know they think so badly of me that I do very little to change their perception of me, its like my body is at work, but my mind is somewhere else. Luckily, I have a very patient manager, and so far he has not made a big deal about my mistakes, but I think my luck is starting to run out. I really need my job, and I am starting to have self doubts about myself. Mind you, I have over eight years of experience, and never had this type of problem with any of my other employers.
