kyniemxotxa · kyniemxotxa

Hey, I have seen many multiplication problems which reverse the ones and tens digits:34*43. Is there a trick for this? If there is, can someone please let me know!!!!!

bradp · Anonymous

regular 2 by 2 or 2 by 3, do yall use the tricks for ending in 5, same tens....and all that. or do you follow teh same routine for multiplication each time? which one is more time efficient?

How do you work questions such as 'how many lines are determined by 11 points, no three of which are collinear?' or 'how many lines are determined by 11 points, only three of which are collinear' thanks in advance, Vinay

i guess one reason is i crammed practice the 2 weeks before district, but i've practice really hard, but i usually make around 60's (100 is considered high here). it's unbelievable how you guys manage over 100 consistently. im looking for advice on how you guys prepare for the test.&nbs...

The Unversity Interscolastic League number Sense Test, J series rounds down at 5. This is contrary to all text books I have seen. I have seen this on 4 separate practice tests. Example : 65000 rounds to 60000 (most textbooks round to 70000) Please send me any insite you...

Back again. So, here goes: 21. How many odd integers are between nine and 46? //Is there any trick to these? or do you just count? 70* 4.1^3 * 5.1^3 72. The sum of the first nine terms of 1 + 3 + 4 + 7 + ... is? Thanks

Hey y'all, it's vinay again. my school decided to take our uil money and give it to football; so, i dont' have any Dr. Numsen tests.

Well, I just now finished the second test. I must say it is going to be slower than the first. Let me know once Zack posts it up, if there are any mistakes on the answer key.

Ok, here's a trick that we need to work on. How do you solve fractions in the form 1/(a*(a+2)) + 1/(a(a+4)) + 1/((a+1)(a+4)) at the state meet, the question was 11/15+11/21+11/28 it looks like you multiply the numerator by 3 and the denominator is the second denominator minus 1, but how do you...
