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
