What math test do you take?  I'm in Algebra 1 and I only remember 1 question.  It's impossible.\n\nSomeone has a total of 100 coins in dimes and quarters.  The total value adds up to $14.05. How many quarters does she have?\n\nA) 27 (I chose this-it's a dollar off)\nB) 40\nC) 56\nD) 79 (I forget-it's way too high)\n\nWell, that's all I have.  Bye bye!\n\nThanks to the guy who solved that.  I won't get a zero now!

I think the easiest way to know whether or not you add is by picturing a number line that is negative on the left and positive on the right with zero in the middle.\nif you subtract, then you move left\nif you add, then you move right.\n\n\n\nMemorize this!\n+ + makes +\n+ - makes -\n- + makes -\n- - makes +\n\nexample:\n1+(+2)=1+2\n1+(-2)=1-2\n1-(+2)=1-2\n1-(-2)=1+2\n\nanother example:\n(-1) + (+2) = (-1) + 2 = 2 - 1\n(-1) + (-2) = (-1) - 2 = -(1+2)\n(-1) - (+2) = (-1) - 2 = -(1+2)\n(-1) - (-2) = (-1) + 2 = 2 - 1\n\ntry these, and we'll tell you if you got it\n4 - (-5) =____\n6 - 7 = _____\n-9 - 8 = ______\n-3 - (-5) = _______

So where's that starting point?  Either we start (yesterday) with Mary having $785.63 we subtract $57. and $125. for 603.63.  Then we add $57.25 for a total of 660.88 (B) \nOR\nwe start we $785.63 (today) anb subtract $57. and $125 for $603.63 (C).  The $57.25 doesn't matter cause Mary did that yesterday....

Well, you got me stumped!\n\n-------------------------------------\n\nI started working it out and got pretty far.\n\nThe above given information might be incorrect.  Maybe?  I don't know.\n\nI tried it several times.  I even double and triple checked my work!\n\n---------------------------------------------\n\nThis is as far as I got and then I got stumped:\n(D-E) (B+C) = (10J + AFGH) / A\n\n------------------------------------------------------\n\nGreat question!\n\nI look forward to the continuing discussion.\n\nI love the way you worded your question.  Right on!!!\n\nKeep those challenge questions coming!  ;o}

I'd like to tell you a couple of tricks for getting ABOUT the right answer, which is often all you need, for instance when you're buying something and want to guard against a major cashier's error.\nMultiplying two numbers: Try to simplify the problem. Say it's 15 cans of something at 39 cents a can. Well 39 is pretty close to 40, so you get 15*40=$6.00. Or if you want it exactly, 15*40=$6.00 but subtract 15 cents because you added it when you simplified. $6.00 - $0.15 = $5.85. That's a lot easier than mentally multiplying 15 by 39.\nOften there seems to be no way to simplify the problem. Like 34 * $0.57. Well see what happens if you decrease one a little and increase the other by the same percentage. Say we take 34 down to 30, that's a little more than 10% less. Then what's a little more than 10% of 57? About 7. So we add 7 to 57, and we have 30 * $.64 = $19.20. The actual answer is $19.38. Again, not too bad. Or a 3-digit number: Try $3.79 * 18. OK, lets put $3.79 up to $4.00, about a 5% increase. Then take about 5% off 18 and it's 17. $4.00 * 17 = $68.00, compared to the exact answer of $68.22. \nHow about when you have a bunch of different items in the supermarket cart and you want the approximate total? Just keep track of the dollars and remember the cents as simple fractions of a dollar. So if you have these items: $1.39, $3.75, $2.19, $7.63, you say 1 & 1/3 plus 3 & 3/4 is 5 & a little; plus 2 & a little is 7 & 1/2; plus 7 & 1/2 is 15. The actual total is $14.96. Again, not too bad, although it won't always be this close. I hope you can use these. It gets easier with practice.
