2+2-2

The calculation follows the order of operations, which is parentheses first, then exponents, followed by multiplication and division (from left to right), and finally addition and subtraction (from left to right). This is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).

Given the expression 2 + 2 - 2, you would perform the calculations from left to right because there are only addition and subtraction operations involved.

First, you would add:

2 + 2 = 4

Next, you would subtract:

4 - 2 = 2

So the answer is 2.
