Integer Numbers -They are all positive and negative whole numbers, which do not include any fractional or decimal part.
Consist of the set of numbers: {…-4, -3, -2, -1, 0, 1, 2, 3, 4…}
If a number has no sign it usually means that it is a positive number.
Example {0,1,2,3,4,5,6.....}
Adding and Subtracting integers
Adding integers
(+)+(+) = + sum
(-)+(-) = - sum
(+)+(-) or (-)+(+) = difference of numbers with signs of larger number in absolute value.
Subtracting Integers
(-)(-) = + sum
(-)(+) = - sum
Since 0 is a positive number and -4 is a negative number, we can represent them as (-)(+) = - sum
0+(-4) Equation
0-4 Simplify
-4 = Solution
