- positive and negative whole numbers including zero
eg. 1, 7, 63, 23783457, -9, -985, -56422147, 0
Integers are not decimals, fractions, percent, ratio
eg. 65%, 7.6, 1:2, 3/4 are not integers
Zero pair
- a pair of integers representing +1 and -1
eg. + - this pair represents zero pair because (+1) + (-1)= 0
Examples of zero pair
(+2) + (-2)=0
(+3) + (-3)=0
Predict the sum of any pair of opposite integers.
Opposite integers are two integers with the same numeral, but different signs.
eg. +2 and -2 or +123 and -123
What if the negative comes first.
(-8) + (+8)= 0
It's still going to be zero.
Here is some problems for practice..
(+5) + (-1)=
(+15263) + (-15263)=
(-6) + (+8)=
