                    Lesson 1

                                                                                               

4 x 3               =  +12

4 x ( -3 )         =  -12

( - 4 ) X  3       =  -12

( - 4 ) X ( - 3 )  = +12   

1. The product of two integers with same     sign is a positive integer.

2. The product of two integers with

       different signs is a negative integer.

 

                                                            Problem:                   Fill in the blanks with correct sign:

 

                                                                             - 2 x 8 =        16

 

                                                                               Step 1: First digit has negative sign and second is positive

 

                                  

                                                                               Step 2: The product of two integers with different signs is a negative integer.

                        

                                                                            

                     Step 3: The answer is:  -16

                                                           

                                                                                                               

 

                                                            Try two practice problems:  

 

                                                                                               Fill in the blanks

 

A. (- 4) x (- 2) = ___ 8

 

B. (+ 4) ÷ (- 2) = ___ 2
