from the point on the number line that represents the integer to the origin is a.

Using this idea answer the

following.

a. Explain why a 2 b is the distance between the points that represent the integers a and b.

b. One way to define less than for integers is as follows: a , b if and only if a is to the left of b on the number line.

Consequently b . a if and only if b is to the right of a.

Use these ideas to mark on a number line all integers

x such that:

(i) x , 5 (ii) x , 1

(iii) x $ 5 (iv) x.21

Draw a number line, starting at zero, marking 1,2,3,4,5,6,7...10

Somewhere put a b above one of the numbers. To the left of b, between zero and b, put an a above a number.

a) The distance from the origin to b is The number at point b. The distance from the origin to a is the number by a.

The question is, how far is it from a to b?

WEll, if we subtract a from b, we get that distance.

b)I dont understand the symbols above. Sorry.
