Integers are whole numbers that can be positive, negative, or zero, but not fractions or decimals. A negative number is less than zero and is represented by a minus sign (-). The number line is used to show integer operations and the relative positions of positive and negative numbers. In the place value system, the value of each digit in a number depends on its place, with ones, tens, hundreds, and so on. Integer rules state that adding or subtracting two numbers of the same sign results in a positive number, while opposite signs can result in a positive or negative number depending on the values.

3. Integers
A positive number , a negative number
or a zero but not a fraction or a decimal.
A whole number
Whole numbers greater than zero are
called positive integers. These numbers
are to the right 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.
