\n" ); document.write( "\n" ); document.write( " When working with rules for positive and negative numbers, try and think of weight loss, or poker games, or baying items to help solidify 'what this works'.
\n" ); document.write( " Using a number line showing both sides of 0 is very helpful to help develop the understanding of working with positive and negative numbers/integers.\r
\n" ); document.write( "\n" ); document.write( "with positive and negative numbers (integers) you can do: adding, subtracting, multiplying and dividing\r
\n" ); document.write( "\n" ); document.write( "Adding Rules:\r
\n" ); document.write( "\n" ); document.write( "Positive + Positive = Positive
\n" ); document.write( "5 + 4 = 9 \r
\n" ); document.write( "\n" ); document.write( "Negative + Negative = Negative\r
\n" ); document.write( "\n" ); document.write( " (- 7) + (- 2) = - 9 \r
\n" ); document.write( "\n" ); document.write( "Sum of a negative and a positive number: Use the sign of the larger number and subtract\r
\n" ); document.write( "\n" ); document.write( "(- 7) + 4 = -3\r
\n" ); document.write( "\n" ); document.write( "Subtracting Rules:\r
\n" ); document.write( "\n" ); document.write( "Negative - Positive = Negative\r
\n" ); document.write( "\n" ); document.write( "(- 5) - 3 = -5 + (-3) = -8\r
\n" ); document.write( "\n" ); document.write( "Positive - Negative = Positive + Positive = Positive\r
\n" ); document.write( "\n" ); document.write( " 5 - (-3) = 5 + 3 = 8
\n" ); document.write( "Negative - Negative = Negative + Positive = Use the sign of the larger number and subtract (Change double negatives to a positive)\r
\n" ); document.write( "\n" ); document.write( "(-5) - (-3) = ( -5) + 3 = -2
\n" ); document.write( "(-3) - ( -5) = (-3) + 5 = 2\r
\n" ); document.write( "\n" ); document.write( "Multiplying Rules:\r
\n" ); document.write( "\n" ); document.write( "Positive x Positive = Positive
\n" ); document.write( " 3 x 2 = 6
\n" ); document.write( "Negative x Negative = Positive
\n" ); document.write( "(-2) x (-8) = 16
\n" ); document.write( "Negative x Positive = Negative
\n" ); document.write( " (-3) x 4 = -12
\n" ); document.write( "Positive x Negative = Negative
\n" ); document.write( " 3 x (-4) = -12\r
\n" ); document.write( "\n" ); document.write( "Dividing Rules:\r
\n" ); document.write( "\n" ); document.write( "Positive ÷ Positive = Positive
\n" ); document.write( " 12 ÷ 3 = 4
\n" ); document.write( "Negative ÷ Negative = Positive
\n" ); document.write( "(-12) ÷ (-3) = 4
\n" ); document.write( "Negative ÷ Positive = Negative
\n" ); document.write( " (-12) ÷ 3 = -4
\n" ); document.write( "Positive ÷ Negative = Negative
\n" ); document.write( " 12 ÷ (-3) = -4
\n" ); document.write( "
