On the number axis, the number of integer points whose distance from the origin is less than 2, the number of positive integer points which are not more than 2 is y, and the number of integer points which are equal to 2 is Z. find the value of X + y + Z

On the number axis, the number of integer points whose distance from the origin is less than 2, the number of positive integer points which are not more than 2 is y, and the number of integer points which are equal to 2 is Z. find the value of X + y + Z

On the number axis
There are three integer points whose distance from the origin is less than 2: 1, - 1 and 0
The number of positive integer points not greater than 2 are: 1 and 2
The number of integer points equal to 2 are: 2, - 2
So x, y and Z are 3, 2 and 2, respectively
x+y+z = 3 + 2 + 2 = 7
