subtracting, adding, multiplying, and dividing intergers!

ADDITION RULES!!!
1. IF THE SIGNS ARE THE SAME THEN ADD.
2. IF THE SIGNS ARE DIFFERNT THEN SUBTRACT AND KEEP THE SIGN OF THE BIGGER #!

OK LEYS TRY SOME!
LETS SAY YOU HAD THE PROBLEM 6+-4=. YOU WOULD FOLLOW ADDITION RULE # 2. SO YOU WOULD SUB. 6- -4=2. THEN YOU KEEP THE SIGN OF THE BIGGER #. THE BIGGER # IS 6 AND 6 IS POSSITIVE IN THIS PROBLEM SO THE ANSWER IS JUST 2! DO YOU GET IT? IF YOU DONT HERE ARE SOME MORE EX. FOR YOU!
-6+-8=-14 THIS ONE IS DIFF. YOU FOLLOW RULE # 1!

-5+3=-2


SUBTRCTION RULES!!!
1. ALWAYS DO PLUS THE OPPISITE TO THE SECOND #!
2.THEN FOLLOW ADDITION RULES TO DO REST.

LETS TRY SOME!!!!
OK. SO THIS ONE IS A LITTLE BIT DIFFERENT THAN ADDITION. YOU HAVE TO DO PLUS THE OPPISITE. NOW SAY YOU HAD THE PROBLEM OF -8-5=. YOU DO PLUS THE OPPISITE. SO NOW YOUR PROBLEM LOOKS LIKE THIS... -8+-5 BECAUSE YOU CHANGE THE SUBTRACTION SIGN TO ADDITION AND YOU ALSO CHANGE THE POSSITIVE 5 TO A NEGATIVE 5. NO YOU JUST FOLLOW THE RULES FOR ADDITION SO NOW IT COMES OUT TO BE... -8+-5=-13. IF YOU STILL DO NOT UNDERSTAND HERE ARE SOME PRACTICE PROBLEM
(NOW THIS FIRST ONE IS GOING TO BE A LITTLE BIT DIFFERENT.)

-7- -3=... -7+3= -10
-5-4=...-5- -4=-1


MULTIPLICATION RULES!!!
1. IF THE SIGNS ARE THE SAME THEN MULTIIPLY AND THE ANSWER WILL BE A POSSITIVE.
2.IF THE SIGNS ARE DIFFERENT THEN MULTIPLY AND THE ANSWER IS A NEGGATIVE.

NOW LETS TRY SOME!!!
O.K. LETS SAY YOUR PROBLEM IS -6*5=. YOU WOULD MULTIPLY THE #'S LIKE THEY ARE BOTH POSSITVES AND THEN YOUR ANSWER WILL BE A NEGGATIVE BECAUSE THE SIGNS ARE DIFF. SO 6*5=30. AND THE 30 WOULD BECOME A NEGGATIVE SO YOU ANSWER IS -30. IF YOU STILL DONT GET IT THEN HERE ARE SOME PRACTICE PROBLEMS.(FOR THE FIRST ONE YOU WILL HAVE TO FOLLOW MULTIPLICATION RULE #1)

-4*-2= 8
-7*3=-21

DIVIDING RULES!!!!!!!
1.IF THE SIGNS ARE THE SAME THEN YOU DIVIDE AND THEN YOUR ANSWER WILL BE POSSITIVE.
2. IF THE SIGNS ARE DIFFERENT THEN YOU DIVIDE AND THE ANSWER WILL BE A NEGGATIVE.

LETS TRY SOME!
SO HERE IS YOUR PROBLEM -10/5= YOU WOULD FIST JUST DIVIDE THE #'S LIKE THEY ARE BOTH POSSITIVE SO...10/5=2. SO THE SIGNS ARE DIFFERENT SO THE ANSWER IS A NEGGATIVE SO YOUR ANSWER IS... -2! NOW IF YOU STILL DONT UNDERSTAND COMPLETELY HERE IS SOME MORE PRACTICE. (THE FIRST ONE IS DIFFERENT YOU WILL HAVE TO FOLLOW DIVISION RULE #1)

-4/-2=...2!
-9/3=...-3!
