US Version

It's difficult to choose only four numbers. Just try plugging in different numbers.

UK Version

It's difficult to choose the correct numbers, even though there are only four of them. Just keep trying different possibilities.

US Version

Think of two sets of two numbers that produce the same value when the numbers in one set are multiplied and the numbers in the other set are added together, and vice-versa.

UK Version

Think of two pairs of two numbers that produce the same value when the numbers in one pair are multiplied and the numbers in the other pair are added together, and vice versa.

The two numbers on each side of the equation should produce the same result when they are multiplied as when they are added together, so large numbers won't work.

US Version

When the solution to the top equation is six, the solution to the lower equation is five.

UK Version

When the solution to the top equation is six, the solution to the bottom equation is five.

## Solution

### Incorrect

It's a combination of simple numbers. Just keep trying.

### Correct

Brilliant!

US Version

Here is one possible solution. The right half and left half of the equation are interchangeable. Since they involve addition and multiplication, the equation is viable even if the two numbers on the left side swap positions, or it the two numbers on the right side swap positions.

UK Version

Here is one possible solution. The right and left halves of each equation are interchangeable. Additionally, since each half of the equations involves the addition or multiplication of a pair of numbers, the order of numbers in each pair can be switched without affecting the overall result.
