copyright©amberpasillas2010 Step 2: Line up the decimals Step 3: If needed, put zeros in as place holders Step 4: Add decimals Step 5: Bring decimal down Step 1: Use shortcuts for negatives The answer is NEGATIVE – + – = – The signs are same so take the SUM ! Step 6: Determine the sign of the answer

copyright©amberpasillas2010 – The signs are different so take the DIFFERENCE! 4 Step 1: Line up the decimals 0.67 – 0.53 Step 2: If needed, put zeros in as place holders Step 3: Subtract decimals Step 4: Bring decimal down. 10- The answer is negative because you started with MORE NEGATIVES! Step 5: Determine the sign of the answer
