I can prove why 1 = 2

* Lets say y = x

* Multiply through by x xy = x2

* Subtract y2 from each side xy - y2 = x2 - y2

* Factor each side y(x-y) = (x+y)(x-y)

* Divide both sides by (x-y) y = x+y

* Divide both sides by y y/y = x/y + y/y

* And so... 1 = x/y + 1

* Since x=y, x/y = 1 1 = 1 + 1

* And so... 1 = 2

How is this possible ?

Step 5 is invalid, because we are dividing by (x-y), and since x=y, we are thus dividing by 0. This is an invalid mathematical operation (division by 0), and so by not following basic mathematical rules

Find three whole, positive numbers that have the same answer when multiplied together as when added together.

1,2, & 3

1 x 2 x 3 = 6 and 1 + 2 + 3 = 6

What is the value of 1/2 of 2/3 of 3/4 of 4/5 of 5/6 of 6/7 of 7/8 of 8/9 of 9/10 of 1000?

100. Looks hard? Don't worry, just work it backwards and you'll find it very easy.

Can you find four consecutive prime numbers that add up to 220?

47 + 53 + 59 + 61 = 220

Ross five friends Rachel,Monica Phoebe,Joey and Chandler lives in the same road.

Rachel lives in house:A , Monica lives in house:B , Phoebe lives in house:C , Joey lives in house:D , Chandler lives in house:E

Mathematically

B*C*D = 1260

B + C + D = 2E

2A = E

The road numbers run from 2 to 222.

Can you tell the house number of each of Ross's friends ?

Rachel lives in House no.36

Monica lives in House no.4

Phoebe lives in House no.9

Joey lives in House no.35

Chandler lives in House no.24

Can you arrange four 9's and use of atmost 2 math symbols , make the total be 100?

99 / .99
