Read More →Rules – Addition of Integers There are two conditions when adding integers. Rule 1: When integers have same sign. Rule 2: When integers have opposite sign. (a) When integers have same sign. (b) When integers have opposite sign. a. Integers having (same)positive sign. When we add two positive integers means both […]
Read More →Positive Integers on Number Line A number line shows positive integers on the right side of the zero. We understand the concept in a better way with the help of examples. Example: Below number line represents integer 4 an d 4 is a positive integer, so, 4 is right side of 0. […]
Read More →Negative Integers on Number Line A number line shows negative integers on the left side of the zero. We understand the concept in a better way with the help of examples. Example: Below number line represents integer -5 and -5 is a negative integer, so, -5 is left side of 0. Similarly, -3 is a negative integer […]
Read More →Addition and Subtraction of Integers on number Line Steps for addition and subtraction of integers on a number line are as follows. Step1: Draw a number line. Step 2: For addition and subtraction, we clearly understand that, For a positive number, we have to move right from zero on the number line. For a negative […]
