Operations on Integers Negative and Positive Numbers MULTIPLICATION
Positive Negative
Rules for Multiplication of Integers S D ifferent sign = Negative ame sign = Positive If we multiply 2 integers with the same sign then the answer is POSITIVE. If we multiply 2 integers with the different sign then the answer is NEGATIVE.
SAME SIGN = POSITIVE If we multiply 2 integers with the same sign then the answer is POSITIVE.
CASE 1: A POSITIVE number MULTIPLIED to a POSITIVE number is POSITIVE. 5 • 10 = ??
CASE 1: A POSITIVE number MULTIPLIED to a POSITIVE number is POSITIVE. 5 • 10 = ??
CASE 1: A POSITIVE number MULTIPLIED to a POSITIVE number is POSITIVE. 5 • 10 = 50
CASE 2: A NEGATIVE number is MULTIPLIED to a NEGATIVE number is POSITIVE. (-7) • (-6) = ??
CASE 2: A NEGATIVE number is MULTIPLIED to a NEGATIVE number is POSITIVE. (-7) • (-6) = ??
CASE 2: A NEGATIVE number is MULTIPLIED to a NEGATIVE number is POSITIVE. (-7) • (-6) = 42
DIFFERENT SIGN = NEGATIVE If we multiply integers with the different sign then the answer is NEGATIVE.
CASE 3: A POSITIVE number MULTIPLIED to a NEGATIVE number is NEGATIVE. 7 • (-5)= ??
CASE 3: A POSITIVE number MULTIPLIED to a NEGATIVE number is NEGATIVE. 7 • (-5)= ??
CASE 3: A POSITIVE number MULTIPLIED to a NEGATIVE number is NEGATIVE. 7 • (-5)= -35
CASE 4: A NEGATIVE number is MULTIPLIED to a POSITIVE number is NEGATIVE. (-8) • 2 = ??
CASE 4: A NEGATIVE number is MULTIPLIED to a POSITIVE number is NEGATIVE. (-8) • 2 = ??
CASE 4: A NEGATIVE number is MULTIPLIED to a POSITIVE number is NEGATIVE. (-8) • 2 = -16
DIFFERENT SIGN = NEGATIVE SAME SIGN = POSITIVE
Operations on Integers Negative and Positive Numbers DIVISION
Rules for Division of Integers S D ifferent sign = Negative ame sign = Positive If we divide 2 integers with the same sign then the answer is POSITIVE. If we divide 2 integers with the different sign then the answer is NEGATIVE.
DIFFERENT SIGN = NEGATIVE SAME SIGN = POSITIVE
SAME SIGN = POSITIVE If we divide 2 integers with the same sign then the answer is POSITIVE.
CASE 1: A POSITIVE number DIVIDED to a POSITIVE number is POSITIVE. 10 ÷ 5 = ??
CASE 1: A POSITIVE number DIVIDED to a POSITIVE number is POSITIVE. 10 ÷ 5 = 2 ÷
CASE 2: A NEGATIVE number is DIVIDED to a NEGATIVE number is POSITIVE. -18 ÷ (-6) = ??
CASE 2: A NEGATIVE number is DIVIDED to a NEGATIVE number is POSITIVE. -18 ÷ (-6) = 3 ÷
DIFFERENT SIGN = NEGATIVE If we divide integers with the different sign then the answer is NEGATIVE.
CASE 3: A NEGATIVE number is DIVIDED to a POSITIVE number is NEGATIVE. -24 ÷ 6 = ??
CASE 3: A NEGATIVE number is DIVIDED to a POSITIVE number is NEGATIVE. -24 ÷ 6 = -4 ÷
CASE 4: A POSITIVE number is DIVIDED to a NEGATIVE number is NEGATIVE. 32 ÷ (-4) = ??
CASE 2: A POSITIVE number is DIVIDED to a NEGATIVE number is NEGATIVE. 32 ÷ (-4) = ?? ÷
