qualities of a good mathmatician

TOP 3 :

- hard working / diligent
- intelligent / smart
- focused

its important to work hard and be diligent because
its the basics ..
if youre lazy , the work wont be finished on time
and thats not a good work habit

its important to be intelligent / smart because
it is neccessary to be able to comprehend the question
and be able to answer it properly
showing work proves that you know how to do the question

its important to be focused and concentrated
because if there is a distraction , the work may not be finished
or may have mistakes because they didnt pay attention to their work

favourite math question number.three

17) If w is a positive integer and w^3 = 9w , then w^5 is equal to ..

for this question , i just guessed 3 randomly
and ..

3^3 = 27
9 x 3 = 27

so then ,

3^5 is 243

to solve this question i just used
guess and check
and somehow , my first guess was correct
YAY :)

math contest question

soo , there was a math contest
and i epically failed under the time limit and
got like 60 points :(
i think i couldve done waaaaay better
if there had been more time ..
i couldnt even check my answers or pick of a logical answer to guess ..
i did terrible and was mad ..
i felt so stressed during one question
that i felt like yelling and screaming in the middle of the contest LOL

anyways , one of the questions i can do
without using any diagrams is number ten

10) there are 400 students at pascal h.s., where the ratio of boys to girls is 3 : 2. there are 600 students at fermat c.i., where the ratio of boys to girls is 2 : 3. when considering all students from both schools , what is the ratio of boys to girls ?

so heres the work ::

pascal -
400 / 5 = 80
80 x 3 = 240 boys
80 x 2 = 160 girls

fermat -
600 / 5 = 120
120 x 2 = 240 boys
120 x 3 = 360 girls

the total number of boys and girls
480 : 520
if this ratio is reduced ,
it becomes 12 : 13
hence , the answer is B) 12 : 13

yay ! what an easy question ..
i epically failed this question
because , in the rush ,
i misread the numbers and made a miscalculation ..
becuase , my stupid brain wasnt reading properly
so i didnt get this answer
although i figured something was wrong -
because none of the amounts matched
i couldnt find the problem
anyways , yah ..
hopefully ill do better next time :)
