More about Integers

Multiplying Integers

1. Always multiply the absolute values.

2. Use the rules of if it is the same signs it is positive and if it is different sign it is negative.

3. The result takes the sign of the integer with the greater absolute value.

Dividing Integers

1. Always divide the absolute values.

2. Use the rules if it is the same signs it is positive and if their are different sign it is negative.

3. The result takes the sign of the integer with the greater absolute value.

Examples of Dividing Integers

1) 6 ÷2= -3 Because you first divide 6÷2=3 and 6 is the greater absolute value so you put the negative sign to the 3 so it is -3


2) -8÷ -2 you divide 8÷2 which is 4 and the numbers have negative and negative which is positive sign so it stays in 4.


3) -15÷-3 you divide 15÷3 which is 5 and then tou look at the sign so negative and negative = positive signs so you leave the answer in 5
