```NO CALCULATORS!!!!!!!

Integers are the whole numbers and their
opposites (no decimal values!)
Example: -3 is an integer
Example: 4 is an integer
Example: 7.3 is not an integer

Adding integers comes down to two rules
Rule 1: If the signs (+ or -) are the same, simply
add the numbers and keep that value
Example: -4 + -8 = -12 (because 4 + 8 is 12)
Rule 2: If the signs are different, simply
subtract the number closest to zero from the
number further away from zero and keep the
sign of the number furthest from zero
Example: 3 + -7 = -4 (because 7 – 3 is 4)


Subtraction and addition are friends, so
subtraction just changes itself to addition by
changing the second number’s sign. Make sure
you follow the addition rules after that.
Example: -4 – 6 means -4 + -6 = -10

They, too, are friends so they share the rules
Rule 1: When the signs are the same (either + +
or - -) simply do the operation and the answer
will be positive
Example: -25 ÷ -5 = 5 (since it is - -)
Rule 2: When the signs are different (either + or - +) simply do the operation and the answer
will be negative
Example: -4 • 8 = -32 (since it is - +)
