What are integers
WHAT ARE INTEGERS

  • Integers are any numbers from a set.

  • Integers are also negative and positive numbers.

  • Positive integers are greater than zero.

  • They can be written with or without a plus sign

  • Negative are integers less than zero.

  • They are written with a minus sign.

  • Zero is nether a positive or a negative.


How to multiply integer
How to multiply integer

  • Multiplication is the same as repeated addition.

  • When you multiply with a negative and a positive the sign is different.

  • The product of two positive integers is positive

  • You can use a pattern to find the product of two negative integers.

  • Negative * positive = negative

  • Negative * negative = positive

  • ex. (2)(-3)= -6


How to divide integers
How to divide integers

  • When finding the quotient of two integers you can use related multiplication sentence.

  • Division of Integers is similar to division of whole numbers (both positive) except the sign of the quotient needs to be determined.

division

multiplication

  • -35 / -1

  • -117 / -3

Lets try and solve these problems. then you will get a quiz to see what you know. Then when you are done I want you to tell me the difference between dividing and multiplying integers and don’t worry we are almost done.


Help with division
Help with division

  • 35/-1

    Step 1.how many times can 1 go into 3?

    Step2.so you carry the 3 and subtract and you get zero.

    Step 3. then you do the same with the 5.

  • -117/-3

  • Step 1. you line up 117 and 3. then you multiply.

  • Step 2.You start from the back. 7(3) is 21.so you leave the 1 and carry the 2.

  • Step 3. 1(3) is 3 plus 2 is 5. then 1(3) is 3 so you get 3. then your answer is 351.

I hope you were paying attention because now you have a quiz .there is no help on this. GOOD LUCK
