During math class, Mr. Backe talked about how to add, subtract and multiply rational numbers.

Step 1: Find a common denominator.
Step 2: Make equivalent fractions.
Step 3: Use sign rules to,
Step 5: Simplify if possible.

Subtraction:
Step 1: Find a common denominator.
Step 2: Make equivalent fractions.
Step 3: Use sign rules to,
Step 4: Subtract the numerators.
Step 5: Simplify if possible.

Multiplication:
Step 1: Multiply the numerators by the numerators and denominators by the denominators. Be aware of the signs.
Step 2: Simplify if possible.

Also, if you guys are having a trouble with your multiplication table still, here's a little something I learned in grade 3.

For the nine's multiplication table, I learned something that really helped me.
First you get 9 and you multiply it by any single digit number.
9 x 7
Now you take the factor (7) and you subtract one from it, so now you have 6. 6 plus what equals 9 ? It's 3. Now you place the two numbers together and get 63.
Sorry if it doesn't really make sense, but this is what I do whenever I need to multiply by 9. Hopefully I helped some of you guys.
