Can you solve this test without a calculator?

Parentheses
Exponents (or powers)
Multiplications and divisions, from left to right
Additions and subtractions, also from left to right
Don't panic, here we only have three operations to manage: multiplication, subtraction and addition. But it is precisely this false simplicity that makes the exercise misleading.

Let's solve it together, step by step

Let's take our time. Here's the operation:
11 – 11 × 11 + 11

We start with multiplication:
11 × 11 = 121

The operation therefore becomes:
11 – 121 + 11

Then we solve the remaining operations from left to right:
11 – 121 = -110

Then,
-110 + 11 = -99

The result
