Question

Which of the following does NOT show an identity property?

2 + 1 = 3

5 ÷ 1 = 5

3 − 0 = 3

4 × 1 = 4

Answer 1

2+1 = 3

Explanation:

The first one

2+1 = 3

the identity properties are :

n+0=n

n-0=n

n/1=n

n*1=n

and the one that does NOT show an identity is 2+1=3

Answer 2

2+1=3 is not an identity property. The rest are because the value equals itself after dividing, subtracting, and multiplying.
