Making careless calculation mistakes

[crusade]

Hey,

While analyzing some of my mistakes, I've found that I tend to make simple calculation errors, which either costs me time or the question. For example, in one of the problems I was able to derive the expression:

3S+3*84+4S+14=476

But while multiplying 3*84+14,instead of computing it as 266, I wrote it as 252+14=276! Then spent about a minute figuring out whether the expression in itself was wrong.

This is just an example, but I find that I keep making similar mistakes. Is there anything that you recommend would help me compute expressions faster as well as avoid careless calculation mistakes?

Thanks!

Thanks!

ironically, my recommendation would be to compute these expressions more slowly.
i think your desire to "compute expressions faster" is the actual source of 99.9999% of these mistakes. just slow down a bit, be more careful with your basic arithmetic, and bam! you won't make as many errors.

Thanks Ron -- you're right, I may be rushing through them.

These are sometimes become so frustrating that i leave it for sometimes and then after getting fresh i again go through it so just don't get panic and do calmly.
