Accentuate the Negative Investigation 3
Multiplying and Dividing Integers ÷ ÷ X X

3.1-2 Introducing Multiplication of Integers
And Division Algorithm Example Same Signs Product is positive Quotient is positive 2 x 3 = 6 -2 x -3 = 6 12 ÷ 2 = 6 -12 ÷ -2 = 6 Different Signs Product is negative Quotient is negative 2 x -3 = -6 -2 x 3 = -6 12 ÷ -2 = -6 -12 ÷ 2 = -6

‘Multiplication’ Flap of Foldable
Left side Same Signs Product is Positive Ex. 2 x 5 = 10 Ex. -6 x -3 = 18 Right side Different Signs Product is Negative Ex. -7 x 3 = -21 Ex. 2 x -1 = -2

‘Division’ Flap of Foldable
Left side Same Signs Quotient is Positive Ex. 12 ÷ 4 = 3 Ex. -15 ÷ -3 = 5 Right side Different Signs Quotient is Negative Ex. -20 ÷ 10 = -2 Ex. 45 ÷ -15 = -3

Same Signs Product is Positive Ex. 2 x 5 = 10 Ex. -6 x -3 = 18

Different Signs Product is Negative Ex. -7 x 3 = -21 Ex. 2 x -1 = -2

Same Signs Product is Positive Ex. 2 x 5 = 10 Ex. -6 x -3 = 18

Different Signs Product is Negative Ex. -7 x 3 = -21 Ex. 2 x -1 = -2

Same Signs Product is Positive Ex. 2 x 5 = 10 Ex. -6 x -3 = 18

Different Signs Product is Negative Ex. -7 x 3 = -21 Ex. 2 x -1 = -2

Same Signs Quotient is Positive Ex. 12 ÷ 4 = 3 Ex. -15 ÷ -3 = 5

Different Signs Quotient is Negative Ex. -20 ÷ 10 = -2

Same Signs Quotient is Positive Ex. 12 ÷ 4 = 3 Ex. -15 ÷ -3 = 5

Different Signs Quotient is Negative Ex. -20 ÷ 10 = -2

Same Signs Quotient is Positive Ex. 12 ÷ 4 = 3 Ex. -15 ÷ -3 = 5

Different Signs Quotient is Negative Ex. -20 ÷ 10 = -2
