Subtracting Integers

Subtracting Integers 

Rule for subtracting integers: add the opposite or changing the second integer of the equation and adding.

Today, we have 3 examples given to help you understand what to do.

#1: (+9) - (-5)

#2: (-7) - (+5)

#3: (-6) - (-4)

Question #1: (+9) - (-5) = ?

You have 9 positive chips.

 You can't take away 5 negative chips, so you need to make 5 'zero pairs'.

 After making 5 zero pairs, take the 5 negative chips away.

In the end, the answer will be (+14).

(+9) - (-5) = (+14)

Question #2: (-7) - (+5) = ?

You have 7 negative chips.

Now make 5 'zero pairs'.

With that, take away the 5 positive chips to get the answer.

Therefore, the answer is (-12).

(-7) - (+5) = (-12)

Question #3: (-6) - (-4) = ?

You have 6 negative chips.

But instead of making 'zero pairs', you just simply take away 4 negative chips.

By doing so, you now have the answer (-2).

(-6) - (-4) = (-2)

Now, you have turned into an 'Integer Master' for subtracting!

Adding and Subtracting Fractions With Different Denominators

   Adding and Subtracting Fractions With Different Denominators

When you add a fraction with different denominators, you must first have to find a common denominator. When you are done figuring out what the common denominator is, you can add both fractions. Finding common denominators are easy, but it takes a lot of courage. You have to remember to do the same thing for both numerators and denominators.(what you do to the bottom, you always do to the top) After you do these steps, adding fractions would be easier for you.

Subtracting fractions is like doing adding fractions. The only different thing you have to do is to subtract. You use the same steps but instead of adding, you will do subtracting. As I said before, it will become easier when you practice and practice and it really takes  a lot of courage to do this.

After you figure out the answer to the fractions your adding or subtracting, before handing your work in, you will have to find it's lowest term. Lowest term means when you get a huge fraction and you find it's lowest term. You will then have to find what number your going to use to divide in order to get it's lowest term. I will show you an example below.

Adding and Subtracting Fractions

When you add fractions with unlike denominators you need to make them common, to do that you need to multiply the denominators by 1, 2, 3, 4, 5, 6, etc. (anything that it can be multiplied by). When you do it to the bottom, you HAVE to do it to the top. Now you can simply do the equation. Don't forget to put your answer in lowest terms! When you add fractions with like denominators, you just need to solve the equation. NOTE; you need to put your answers in lowest terms (if it is not already) to do that you need divide it by 1, 2, 3, 4, 5, 6, 7, 8, etc. (anything that it can be divided by).


When you subtract fractions with like denominators, you simply answer the equation. Remember to put it in lowest terms if it's not already. When you subtract fractions with unlike denominators you need to make them common, to do that you need to multiply the denominators by any number that it can be divided by.

Now you're done!
