`2+2-:2`

To compute this, we have to apply the order of operation known as PEMDAS.

In PEMDAS, division comes before addition. So we divide first. Since 2-:2=1, we would have:

`=2+1`

And then, add them.

`=3`

Therefore, `2+2-:2=3` .

In this problem, we would have to use PEMDAS which stands for the order you would have to do the problem in: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. 

In this case, we are dealing with Division and Addition. And, division comes first. 

So, we would have to divide.

`2+2/2 = 2+1`

Then, add.

`2+1 = 3`

TIP: One way you can remember PEMDAS is the acronym ... "(P)lease (E)xcuse (M)y (D)ear (A)unt (S)ally.

PEMDAS.

Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Since we divide before we add, we divide 2/2 first instead of adding 2+2 first.

This gets us to 2+1 = 3.

To solve this problem, it is helpful to use PEMDAS. This means

Parentheses

Exponents

Multiplication

Division

Addition

Subraction

In the order the words go in, is the order you should solve the problem.

Therefore, you first divide 2/2 to get 1 since Division comes before the word Addition in PEMDAS.

Then you add. 2+1=3

The final answer is 3.

Use BODMAS which is 

B Brackets first

O Orders (ie Powers and Square Roots, etc.)

D Division

M  Multiplication

A Addition

S Subtraction 

So, answer is 3.
