Not all actions are performed in the order in which they occur.
The rule is simple:
you multiply before you subtract.
But this… many forget.
They calculate:
8 – 4 = 4
4 – 1 = 3
3 × 3 = 9
And they think the answer is 9.
Others try a different logic…
and find 3.
But in both cases… the numbers don’t add up.
Let’s now do the calculations correctly.
Let’s start with the multiplication:
1 × 3 = 3
Only then do we proceed:
8 – 4 – 3
And here we count from left to right:
8 – 4 = 4
4 – 3 = 1
