Rules For Multiplying And Dividing Integers Multiplication and division of integers rules, examples. Do not subtract integers. you must change the signs: “add the opposite”. keep keep the sign of the first number. change change the subtraction sign to addition. change change the sign of the second number to the opposite sign. if it is positive change to negative. if it is negative change to positive.
Multiplying And Dividing Integers Rules Chart Teaching tips for multiplying and dividing integers. multiplying and dividing integers are foundational skills for algebra 1. using manipulatives helps students formulate conceptual understanding. have students identify the patterns with multiplying and dividing integers so that they can figure out the rules on their own. Adding integers. rule: if the signs are the same, add and keep the same sign. ( ) ( ) = add the numbers and the answer is positive (‐) (‐) = add the numbers and the answer is negative. rule: if the signs are different, subtract the numbers and use the sign of the larger number. Integer multiplication. If a is any integer, then. a ⋅ 1 = a and 1 ⋅ a = a. because multiplying any integer by 1 returns the identical integer, the integer 1 is called the multiplicative identity. in section 1.3, we learned that multiplication is equivalent to repeated addition. for example, 3 ⋅ 4 = 4 4 4 ⏟ three fours.

Division is the inverse operation of multiplication. so, 15 ÷ 3 = 5 because 5 ⋅ 3 = 15. in words, this expression says that 15 can be divided into three groups of five each because adding five three times gives 15. look at some examples of multiplying integers, to figure out the rules for dividing integers. The following diagram shows the rule to multiply and divide integers. scroll down the page for more examples and solutions on multiplying and dividing integers. what will be the sign for the product when we multiply 2 integers together, for example ( 2) × ( 3)? when multiplying signed integers, the following rules for signs apply: ( ) ×.
