Strategies to deal with careless errors?

How do you guys deal with these?
Under high pressure situations I sometimes make these
And i'm talking really, really fundamental things (basic) like interpreting an extremely simple graph correctly or plugging a number into calculator correctly.
Also for maths some really basic calculations like (2+3) (in spesh tech free for example)

Thanks!

my method is a bit unusual but I read the actual questions related to a piece of information before I read the information. This way, I know exactly what to look for and underline, etc when I read the information.

For the questions that you know you could possibly make a lot of mistakes in just take time a bit slower, rushing will make heaps of mistakes. And get through the easy questions with simple calculations first and quickly.

I doubt this would work on the exam because the exam is a lot harder and more pushed for time than SAC's, but on SAC's I do this:
When you have finished the test, read through every question as if you are solving it for the first time. Of course, you have already solved the problem, so you should be able to get it done in about half of the time that it took you to complete it originally (if not less). Cover your working and solve each step in your head. Then look at your working out and see if you got the same answer. If you get a different answer, then check again, but more thoroughly this time.
I can't tell you how many times this technique has saved me
