Math Ans

Fill the boxes below with numbers from 1 to 9 so that vertically, horizontally, diagonally, the sums of the numbers are 15…


Hint: 9 should be the first number u put inside the box..


Answer review…


1st, u know right, to get a sum of 15 with a 9 inside, only thru this equation:

9 + 2 + 4 / 9 + 1 + 5 / 9 + 3 + 3

a

b

c

d

e

f

g

h

i


So, u can only put 9 in either box b , d , f or h, where it only depend on 2 numbers to get a sum of 15…


Let say we put at f,

a

b

c

d

e

9

g

h

i


So, we solve another 4 boxes, ie

a

b

4

1

5

9

g

h

2


Then, diagonally,

4 + 5 + g = 15, so g = 6;

5 + 2 + a = 15, so a = 8, like…

8

b

4

1

5

9

6

h

2


Ok, getting easier n easier….

8 + 4 + b = 15, so b = 3,

6 + 2 + h = 15, so h = 7

8

3

4

1

5

9

6

7

2


BINGO!!!


So so super extremely hyper extraordinarily EASY rite??



I know I m lame, ok, finish my favourite MATHS, lets get back to study BIOLOGY…………


The different between squamous cell Ca n Adeno Ca microscopically is that in

SCC u will find keratin, once squamous cell secrete too much keratin, it will form keratin pearl, which can c as s spot inside the cell…

For Adeno Ca, u will c clearly some gland, and the gland will secrete mucin, so u will c mucin inside the gland…




The different between concentric n eccentric hypertrophy is

In concentrate hypertrophy, the wall thicken from inside and ALSO outside, so, although the wall is thicken, the lumen is very small (formed Onion shape), found in Hypertensive Heart Disease.

In eccentric hypertrophy, the wall is thicken from outside ONLY, so the lumen is very big, found in Cardiomyopathy.

Both oso show cardiomegaly grossly……..



C, now u know the different between MATH n BIOLOGY, so friends, MATHs is fun n interesting rite??
