At first glance, this problem looks incredibly easy.
Just a few numbers.
Nothing complicated.
But here’s the catch…
Most people answer it wrong within seconds.
Why?
Because their brain rushes.
When people see:
160 – 80 ÷ 2
They instinctively go from left to right:
👉 160 – 80 = 80
👉 80 ÷ 2 = 40
And boom… they confidently say 40.
But that’s exactly where they fall into the trap.
Because math doesn’t work like that.
There’s a rule your brain quietly forgets under pressure:
👉 Division comes before subtraction.
So the correct way is:
First:
80 ÷ 2 = 40
Then:
160 – 40 = 120
And just like that…
The answer changes completely.
