Maths is FUN!!

I’ll prove it

Can you prove THIS

W R O N G

+ W R O N G

----------------

= R I G H T

SOLUTION

HINT O = Zero

Can you get 24 from 8, 8 , 3 , 3 using any mathematical symbols you like.

Come on - you CAN do this!

Solution

Try This

What 5 digit number has the following features :-

If we put the numeral 1 at the beginning, we get a number three times smaller than if we put the numeral 1 at the end of the number

Quite tricky this one!

Solution

Birthday Problem

When asked about his birthday, a man said:"The day before yesterday I was only 25 and next year I will turn 28."This is true only one day in a year - when was he born ?

Solution

Dodgy Digit!

The following equation is wrong: 101 - 102 = 1Move one numeral to make it correct

(Hint – look to the sky...)

Solution

DID YOU DO IT?

3 7 0 8 1

+ 3 7 0 8 1

---------

= 7 4 1 6 2

G = 1, N = 9, O = zero R = 7 W = 3

I = 4 H = 6 T = 2

Success?

This is just one solution

Did you manage it?

The Solution . . .

Using an easy equation: 3(100000 + x) = 10x+1 (Why? Well, adding 100000 puts a 1 at the front of a five-digit number, and multiplying by 10 and adding 1 puts a 1 at the end of a number)Solving this gives:10x+1 = 3(100000 + x) 10x+1 = 300000 + 3x 10x = 299999 + 3x7x = 299999x= 299999/7 = 42857The answer is 42857.
