 Accentuate the Negative Big Idea Negative numbers help us to model many real world situations.

**(Essiential Question #4- How do i multiply and divide integers)**

 * __ Mathematical Reflection (pg. 66) __**


==** 1. **** Write a strategy for multiplying two integers. Be sure to consider all possible c ombinations of positive integers, negative integers, and 0. Verify your strategy by finding the following products. **==

Step one, multiply the integers. (13x7= 91) Step two, verify if the integers are positives or negatives (- x - = +), //__**(- x + = -)**__//, (+ x + = +), (+ x - = -). Step three, complete your answer. (- x + = -, -13x7= -91)
 * a.  -13x7=**

Step one, multiply the integers. (11x20= 220) Step two, verify if the integers are positives or negatives (- x - = +), **//__(- x + = -)__//**, (+ x + = +), //__(+ x - = -)__//. Step three, complete your answer. (+ x - = -, 11x-20= -220)
 * b. 11x-20=**

Any integers who multiplies with the integer 0 will have a product that will automaticly turned into 0.
 * c. -12x0=**

Step one, multiply the integers. (18x22= 396) Step two, verify if the integers are positives or negatives //__ **(- x - = +)** __//, (- x + = -), (+ x + = +), (+ x - = -). Step three, complete your answer. (- x - = +, -18x-22=396)
 * d. -18x-22=**

Step one, divide the integers. (126/9= 14) Step two, verify if the integers are positives or negatives (+ / + = +), //__**(+ / - = - )**__//, (- / + = -), (- / - = +). Step three, complete your answer. (+/-=-, 126/-9= -14)
 *  2.  **** Write a strategy for dividing two integers. Be sure to consider all possible combinations of positive integers, negative integers, and 0. Verify your strategy by finding the following quotients. **
 * a. 126/-9=**

Step one, divide the integers. (36/12= 3) Step two, verify if the integers are positives or negatives (+ / + = +), (+ / - = -), (- / + = -), //__**(- / - = +)**__//. Step three, complete your answer. (-/-=+, -36/-12= 3)
 * b. -36/-12=**

Step one, divide the integers. (2592/32= 81) Step two, verify if the integers are postives or negatives (+ / + = +), (+ / - = -), //__**(- / + = -)**__//, (- / - = +). Step three, complete your answer. (-/+=-, -2592/32= -81)
 * c. -2592/32=**

** d. ** **0/18=** Any integers who divides with the integer 0 will have a quotient that will automaticly turned into 0.

** In this unit, Accentuate the Negative, I learned more about multiplying and dividing negative integers. It does have some connection with adding and subtracting, but works a bit more differently. There are some patterns to follow that could help you in solving multiplying and dividing negative integers like, And
