Integer Operations

By Juan Manuel and Sofia

You will learn to Add, Subtract, Multiply and Divide Integers

Adding Integers


  • When you have like signs you add the integers.


  • When you have unlike signs you subtract and stay with the sign of the higher integer.


Examples.



-3 + -2 = -5 2 + 2 = 4

-5 + 10 = 5

4 + 6 = 10

Subtracting Integers


  • When you have like signs you add the integers.


  • When you have unlike signs you subtract and stay with the sign of the higher integer.


Examples.



5 - 3 = 2

2 - 3 = -1

-4 - 3 = -7

Multiplying Integers


  • When you have like signs the answer stays positive and you multiply regularly.


  • When you have unlike signs the answer is negative and you multiply regularly.


Examples.



5 x 4 = 20

-3 x 5 = -15

-2 x -4 = 6

Dividing Integers


  • When you have like signs the answer stays positive and divide regularly.


  • When you have unlike signs the answer is negative and divide regularly.


Examples.



20 ÷ 5 = 4

-15 ÷ 3 = -5

-18 ÷ -6 = 3
