On the number axis, the integer whose distance from the origin is less than 2 is X. the number of integer points not greater than 3 is y. The number of integer points equal to 4 is e. find the value of X + y + E

On the number axis, the integer whose distance from the origin is less than 2 is X. the number of integer points not greater than 3 is y. The number of integer points equal to 4 is e. find the value of X + y + E

Because it's an integer, x = 5 are (0,1) (0, - 1) (1,0) (- 1,0) (0,0). Note that the origin is easy to drop (only less than 2,0 is also less than 2)
Y = 13 are (0,1) (0, - 1) (1,0) (- 1,0) (0,0) (0,2) (0, - 2) (0,3) (0, - 3) (2,0) (- 2,0) (3,0) (- 3,0) z = 4 are (0,4) (0, - 4) (4,0) (- 4,0) respectively, so x + y + Z = 22
Note: it's on the number axis. Remember to see the title clearly. Is it detailed enough
