Worksheet for Locating Integers on a Number Line. Topic: The Number System. Helps Apply and extend previous understandings of numbers to the system of rational numbers. We provide step-by-step solutions for every question.
Sep 17, 2015 · The sum of any three odd numbers equals an odd number. Proof Lets consider three odd numbers a=2x+1 b=2y+1 c=2z+1 where a,b,c are integers and x,y,z integers as well then the sum equals to a+b+c=2*(x+y+z+1)+1 The last tell us that their sum is an odd.
7.NS.1. Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram. 7.NS.2. Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.
This includes the integers labeled on the number line below. (Note that the number line does not stop at -7 and 7 but continues on in both directions as represented by arrows on the ends.) To plot a number on the number line place a solid circle or dot on the number line in the appropriate place. Examples: Sets of Numbers & Number Line Example ...
A number line is one of the most useful models for understanding negative numbers. To add two integers on a number line, go to the first addend and then go in the direction represented by the second addend. Thus, 5 + (-3) is done by starting at 5 and going -3 units from there — that is, three units to the left — to wind up at + 2.
Addition of integers is represented on a number line as "counting up", where counting up a negative number of times is the same as "counting down." Arrows show the sum of two integers on a number line. The sum is the distance |𝒒| from the 𝒑-value (the first addend) to the right if 𝒒 is positive and to the left

A number line can be used to model integer addition. When adding a positive integer, move to the right on a number line. When adding a negative integer, move to the left on a number line. Example 1:The number line shows how to determine 5 1 8.
Thus, we have the integer number line as follows: We can now easily represent integers on the number line. For example, let us represent 5, 7, 2, 3, 4 on the number line. In the figure, the points A, B, C, D and E respectively represent 5, 7, 2, 3 and 4.
