Practice Subtraction

15 – 2 =

Regular Subtraction 15 – 2 =

Regular Subtraction 15 – 2 = 13

Regular Subtraction 15 – 2 = 13 Same as 15 + -2

15 – (-2) = Same as 15 – -2

Subtraction using Integer Rules 15 + (+2) =

Subtraction using Integer Rules 15 + (+2) = 17

2 – 15 =

Subtraction using Integer Rules 2 – 15 =

Subtraction using Integer Rules 2 + -15 =

Subtraction using Integer Rules 2 + -15 = -13

Practice Addition

15 + 2 =

Positive + Positive = 15 + 2 = Regular Addition

Add; Positive answer 15 + 2 =

Add; Positive answer 15 + 2 = 17

-15 + (-2) =

Negative + Negative = -15 + (-2) =

Add; Negative answer -15 + (-2) =

Add; Negative answer -15 + (-2) = -17

15 + (-2) =

Positive + Negative = 15 + (-2) =

Subtract; Positive answer 15 + (-2) =

Subtract; Positive answer 15 + (-2) = 13

-15 + 2 =

Positive + Negative= -15 + 2 =

Subtract; Negative answer -15 + 2 =

Subtract; Negative answer -15 + 2 = -13

Practice Multiplication Same signs = positive Different signs = negative

5 x 7 =

Positive x Positive = 5 x 7 =

Positive answer 5 x 7 = 35

-5 x -7 =

Negative x Negative = -5 x -7 =

Positive answer -5 x -7 = 35

5 x -7 =

Positive x Negative = 5 x -7 =

Negative answer 5 x -7 = -35
