## Two eggs brainteaser

**Difficulty: Taxing**

Jenny found a strange sum written on a piece of paper:

EGG + EGG = PAGE

Each letter represents a different digit, so P might be 1, for example. Can you work out what the sum really is?

**Scroll down or click for a hint, or the answer!**

## Brainteaser hint 1

Writing it upright might make this easier:

EGG

+EGG

PAGE

Look at the ones column and the tens column. Do you see a difference? This could narrow down your options to solve the problem by using algebra, or trial and error.

## Brainteaser hint 2

If you look at just the ones column and the tens column, you’ll see:

GG + GG = GE

Adding GGs together gives two different letters. There must be a 1 being carried!

## Brainteaser hint 3

Still stuck? If carrying a 1, G must be one of these options: 5, 6, 7, 8 or 9.

What answers do you get if you calculate each of these options for GG + GG? What options does that leave for E?

## Brainteaser answer

If you look at the last two digits of each number, you’ll see:

GG + GG = GE

As mentioned in the hints, there must be a 1 being carried!

Looking at just the tens column:

G + G + 1 = 10 + G

G + G = 9 + G

So, G = 9

Then looking at the ones column:

G + G = 10 + E

9 + 9 = 10 + E

So, E = 8

The final sum is:

899 + 899 = 1798

This reveals the final letters:

P = 1 and A = 7
