integers

 integers

negative integers represent values below zero and positive numbers represent values above zero.
example: above and below ground or sea level
      1+(-9)=(-1) is an addition statement
       3-(-1)=4 is a subtraction statement
opposite integers have the same numeral nut different sign like this positive numbers should look like this 3
and negative numbers should look like this (-3)
 (+)+(+)=  (+)-(+)=
(-)+(-)=     (-)-(-)=
(+)+(-)=    (+)-(-)=
(-)+(+)=    (-)-(+)=
    practice with different numerals in each situation
