need help in SAT math!

<p>I hate how I'm still making stupid mistakes on the math portion. I either do a calculation wrong, write down a number wrong, or do something else than what the questions asks for. How do I correct making these careless mistakes? I have plenty of time to finish and I know how to do all of them, it's just that all my wrong answers are from stupid mistakes.</p>

<p>Practice I guess... The more you do the type of questions you make dumb mistakes on, the less likely you are to make dumb mistakes.</p>

<p>um... check ur work?</p>

<p>Yeah... math killed me as well. But, it's not stupid mistakes that get me... it's questions like:</p>

<p>"If there are twelve dots in space, how many different ways can you connect them?"
"How many numbers from 1 to 999 are even and have a three in them?"</p>

<p>I'm so bad at those... plus, my calculator ran out of batteries on the FIRST math question (it never had a 'low battery' icon... it just died out of nowhere).</p>
