ahh, how could I have missed that. it is a2+a1, not the other way around. That's why it's backwards.

You are adding two strings together, so they will be concatenated instead of treated as numbers and added. therefore, a3=="4531"
Stuff like this it would be better just to put in the code playground to test yourself.

But the answer is "3145"
pls recheck it once again and then tell me :)
