My BrainBashers calculator is low on batteries again, and the following multiplication is wrong. Can you correct it?
Each of the numbers has the correct digits, but they have been mixed up.
Luckily, the solution is correct, which makes the task a little easier.

Answer
4,217 x 5,237 = 22,084,429.
Reasoning
The only way the answer can end in 9 is if the two numbers both end in 7 (7 x 7 = 49).
The only way we can reach 22 million is if the two numbers begin with 4 and 5 respectively.
This leaves each number with just 2 options, and the answer is quickly found.
