Integers are positive numbers, negative numbers, or zero, but not fractions or decimals. Positive integers are whole numbers greater than zero to the right of zero on the number line, while negative integers are whole numbers less than zero to the left of zero. Negative numbers are represented by a minus sign and result from a subtraction where the number being taken away is larger. Positive numbers are greater than zero and represented by a plus sign. The number line helps show addition and subtraction of integers.

3. Integers
A positive number , a negative number or a
zero but not a fraction or a decimal.
Whole numbers greater than zero are called
positive integers. These numbers are to the
right of zero on the number line.
Whole numbers less than zero are called
Negative integers. These numbers are to the
left of zero on the number line.

4. Negative numbers
A number less than zero
We use - to show a negative number.
A positive number could change to a
negative if the sum you have is less
than the number you are taking away.

5. Positive numbers
A number greater than zero
We use + to show a positive number
A negative number plus a positive
number will result in a positive number
if the positive number is bigger than the
negative number.

6. Number line
Line marked with numbers used to show
operations
Could be a line to help you calculate
Addition and subtraction.

7. Place value system
The value of a digit depending on it’s
place in a number.
In the place value system there is ones,
tens, hundreds and thousands. It
continues until it reaches infinity.

8. Integer rules
Positive + negative =positive or negative
depending on the question
Negative - negative=positive ,example
-2 - -3=1 It would equal to 0 because
Negative - negative =positive. But If it
was -2 - -1 It would then equal to a
negative because the negative is larger
than the positive.
