Means: you need to �� to find the "," and you need to �� to find the ""

are any numbers than , for example: 1, 2.9, 3.14, 40000

are any numbers than , for example: -1, -2.9, -3.14, -40000

We do consider to be a positive or negative number.
The of any number and its opposite is 0.
If we have number , its opposite is ; then, their sum is
The

refers to whether the number is or , for example:
the sign of is or , and the sign of 442 is or . As you can see, we don�t have to write + sign in front of positive number ( when we see 442, we know it is +442)

Adding Positive and Negative Numbers
When adding numbers of the same sign, we their , and give the result the .

When adding numbers of the signs, we take their absolute values, the from the , and the the sign of the number with the absolute value.
��. the from the ( (+5) has absolute value) and the the sign of the number with the absolute value, number (+5)
Or, you can have this;
��.
Subtracting Positive and Negative Numbers
a number is the same as adding its opposite; we convert the subtracted number to its opposite, and add the two numbers.

the result of subtracting two numbers can be , can be , or can be
Multiplying Positive and Negative Numbers
Simple rules:
+*+ = +��. both numbers are positive, their product will be positive
+*- = -��if one number is positive and the other one is negative,
-*+ = -�� their product will be negative
-*- = +��. both numbers are negative, their product will be positive
Dividing Positive and Negative Numbers
a. If both numbers are positive, we just divide as usual
b. If both numbers are negative, so we divide the absolute value of the first by the absolute value of the second

c. if both number have different signs, so we divide the absolute value of the first number by the absolute value of the second and give this result a negative sign
