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

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

The integers whose distance from the number axis to the origin is less than 2 have - 1, 0, 1, so x = 3; the integers whose distance from the number axis to the origin is not more than 2 have - 2, - 1, 0, 1, 2, so y = 5; the integers whose distance from the number axis to the origin is equal to 2 have - 2, 2, so z = 2, - x + y + Z = 3 + 5 + 2 = 10
