2. next, subtract the number from 50(4) and square the answer(16), an the write the answer(16) after the above(21) to get 2116: your answer.
46^2 = 2116

I'm busy right now, find yer own practice!!!]]> Number Sense Thu, 12 Mar 2009 00:58:29 GMT http://elkinsmath.forummotion.com/number-sense-f8/trick-of-the-day-squaring-numbers-between-41-and-59-t174.htm#1172 http://elkinsmath.forummotion.com/number-sense-f8/trick-of-the-day-squaring-numbers-between-41-and-59-t174.htm http://elkinsmath.forummotion.com/number-sense-f8/trick-of-the-day-adding-fractions-in-the-form-a-b-b-c-c-d-t176.htm Ani
ex. 1 2/3 + 3/4 + 4/5
1. The whole number part will always be 2
2. Square the first numerator, (2^2 = 4), then multiply by last denominator (4 * 5 = 20), then finally subtract by 2 more than the last denominator(20-(5+2) = 13) to get your numerator
3. The denominator is all the denominators multiplied together (3*4*5 = 60)
4. the answer is 2 13/60]]> Number Sense Thu, 12 Mar 2009 20:23:17 GMT http://elkinsmath.forummotion.com/number-sense-f8/trick-of-the-day-adding-fractions-in-the-form-a-b-b-c-c-d-t176.htm#1178 http://elkinsmath.forummotion.com/number-sense-f8/trick-of-the-day-adding-fractions-in-the-form-a-b-b-c-c-d-t176.htm http://elkinsmath.forummotion.com/general-discussion-f3/psat-scores-t128.htm Ani How did the test go?]]> General discussion Fri, 09 Jan 2009 19:07:14 GMT http://elkinsmath.forummotion.com/general-discussion-f3/psat-scores-t128.htm#1009 http://elkinsmath.forummotion.com/general-discussion-f3/psat-scores-t128.htm http://elkinsmath.forummotion.com/mathematics-f10/tip-common-base-problems-t175.htm Ani Occaisionally, these pop up: (base 8)77777 + (base 3)2222 + (base 5)444 = ? Instead of crunching it out in your calculator, you could simply do the following: realize that 8^3 = 1000 in base 8, soo 8^3-1 = 777 in base 8 right? use the above to simplify the problem above to: 8^5-1 + 3^4-1 + 5^3-1 = an easily solavble problem on your calculator. btw, answer is (base 10)32971 Mathematics Thu, 12 Mar 2009 01:02:18 GMT http://elkinsmath.forummotion.com/mathematics-f10/tip-common-base-problems-t175.htm#1173 http://elkinsmath.forummotion.com/mathematics-f10/tip-common-base-problems-t175.htm http://elkinsmath.forummotion.com/number-sense-f8/trick-of-the-day-alex-integrals-and-derivates-using-the-power-rule-t173.htm Alex Tatge Most people you finde who are not in calculus hear the word "integral" and will generally have one of two responses; either they'll shy away from you with a pained look on their face , or stupidly ask "What's an integral?" Well I'm here to teach you all I know about integrals and derivatives. Please note that I am not in Calculus yet, and I may still have some basic mistakes. Also, I cannot do very many problems.
