How did you come up with that answer cavanaugh?

Order of Operations:

Rule 1: First perform any calculations inside parentheses.
Rule 2: Next perform all multiplications and divisions, working from left to right.
Rule 3: Lastly, perform all additions and subtractions, working from left to right.

I should of paid attention in math class...

huh?

me too Hus.

/me sits in a corner wearing a dunce cap

hehe

Very good! Thats correct, 7.

Q: Distances to certain cities are written below.

How far should it be to Cardiff ?

PARIS 300 miles
ROME 400 miles
AMSTERDAM 300 miles
CARDIFF ? miles

0?

200

Where are you starting from?

thats the fun cosmo

4x+2y=200
3x+2y=300
2x+2y=400
5x+3y=300
5x+2y=?

the solution is left for an exercise for the student

ok, Herbie the bookworm has been closed in a book. the book is one of a set of encyclopedias on a shelf, 1-10 in order. if Herbie starts eating from page 1 of volume 1 and eats his way to the last page of volume 10. How far has he traveled (he travels the shortest path)?

each Volume is 2.5 inches thick and each cover is .25 inches thick.

an easy one.

whats the next letter in this sequence?

O T T F F S S _

#87 100

and a classic list

12 = I in a F = Inches in a Foot
7 = D in a W = Days in a Week
26 = L of the A
52 = W in a Y
64 = S on a C B
54 = C in a D with the J
7 = W of the A W
1001 = A N
12 = S of the Z
9 = P in the S S
32 = D F at which W F
88 = P K
13 = S on the A F
18 = H on a G C
90 = D in a R A
200 = D for P G in M
8 = S on a S S
3 = B M (S H T R)
4 = Q in a G
24 = H in a D
1 = W on a U
5 = D in a Z C
29 = D in F in a L Y
40 = D and N of the G F
12 = D of C
39 = B of the O T
5 = T on a F
15 = P in a R T
3 = W on T
66 = B of the B
11 = P in a F (s) T
12 = M in a Y
8 = T on a O
27 = B in the N T
365 = D in a Y
13 = L in a B D
9 = L of a C
60 = M in a H
23 = P of C in the H B
1000 = Y in a M

#87 = #82

Ok... here's the easy ones....


26 = L of the A (Letters of the alphabet)
52 = W in a Y (Weeks in a year)
12 = S of the Z (Signs of the Zodiac)
24 = H in a D (Hours in a day)
29 = D in F in a L Y (Days in February in a leap year)
40 = D and N of the G F (days and nights of the great flood)
12 = D of C (days of Christmas)
39 = B of the O T (books of the Old Testament?)
12 = M in a Y (Months in a year)
365 = D in a Y (Days in a year)
9 = L of a C (lives of a cat)
23 = P of C in the H B (I know this has something to do with the bible, right?)
1000 = Y in a M (Years in a millenium (sp?))

13 = S on the A F (13 stripes on the American Flag)

8 = T on a O  (tentacles on an octopus)

60 = M in a H (minutes in a hour)

 

 

 

The unsolved ones: (Sylvis_cg76: nope h is for human in that one)

64 = S on a C B
54 = C in a D with the J
7 = W of the A W
1001 = A N
9 = P in the S S
32 = D F at which W F
88 = P K
18 = H on a G C
90 = D in a R A
200 = D for P G in M
8 = S on a S S
3 = B M (S H T R)
4 = Q in a G
24 = H in a D
1 = W on a U
5 = D in a Z C
5 = T on a F
15 = P in a R T
3 = W on T
66 = B of the B
11 = P in a F (s) T
27 = B in the N T
365 = D in a Y
13 = L in a B D
23 = P of C in the H B

13 = L in a B D 13 loaves in a baker's dozen
64 = S on a C B 64 squares on a chess board
4 = Q in a G 4 quarts in a gallon
90 = D in a R A 90 degrees in a right angle
18 = H on a G C 18 holes on a golf course

365 = D in a Y 365 days in a year
54 = C in a D with the J 54 cards in a deck with the jokers
8 = S on a S S 8 sides on a stop sign

23 = P of C in the H B are you sure that's not 23 = P of B in the HB for 23 pints of blood in the human body?

I answered 7 on page 3.

1001=AN = 1001 Arabian Nights (Knights?) didn't read it.
88=PK = 88 Piano Keys.

Q 88 is 24.5 inches (page 1 to the last page (2.5x10-2x.25))

32=D F at which W F = 32 degrees Farenheit at which water freezes
1=W on a U = 1 wheel on a unicycle
3=W on a T = 3 wheels on a tricycle

and still going.

11=P on a F(s) T = 11 players on a football team


And 2 more,

9=S F in a S Y
6=O in an I
