There’s a simple math problem making the rounds that seems straightforward but has been causing confusion due to its deceptively tricky nature. This challenge highlights how our mental arithmetic can easily lead us astray. Let’s give it a try:

Start with 1000,

add 40,

then add another 1000,

add 30,

followed by adding another 1000,

add 20,

add a final 1000,

and conclude with adding 10.
