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:


And then, add them.


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.

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







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.
