What is 2/2?

In mathematics, '/' represents division, and also uses the following symbol: `-:`

Now let's solve the question given: `2//2 = 1`

Any number divided by the same number, except for the number '0', will yield an answer of '1'. 

Let's look at several other examples: 

`5//5 =1`

`2000//2000 = 1`

`(-5)//(-5) = 1` 

Also when a negative number is divided by a negative answer the answer is still '1'

`(2/3)//(2/3) = 1`

Also when the same number as a fraction is divided by the same number as a fraction, the answer yield is also '1'

Speaking of fractions, the above question can also be written as a fraction as follows: `2/2`

When we calculate the fraction we get the same answer: 

`2/2 = 1`

The fraction line that differentiates the numerator and the denominator acts as a division line as well. 

SUMMARY: 

2/2 = 1
