Adding two numbers? Break them into usable parts.

Have you ever needed to add two numbers, but for some reason you were not able to add them in your head?  Today's tip will show us how we can break apart two numbers into more user-friendly parts so we can quickly add them with great ease!

Let's look at our first example.  

You are at the dealership getting your oil changed and the technician reminded you that it is time to have tires rotated.  The oil change is $37 and if they rotate your tires, it will cost an additional $29.  How much will you owe if they do both jobs?  

Solution:  

Step 1--Break down $37 to $30 + $7 and $29 to $20 + $9.  

Step 2--Add $30 + $20 = $50.  

Step 3--Add 7 + $9 = $16. 

Step 4--Add $50 + $16 = $66.

Done!  😃

Heres another one to try.

What is 68 + 38?

Step 1--Break down 68 to 60 + 8 and 38 to 30 + 8.

Step 2--Add 60 + 30 = 90.

Step 3--Add 8 + 8 = 16.

Step 4--Add 90 + 16 = 106.

As we can see, this is a very practical way to add two numbers.  Try a few on your own, and remember to show this tip to a friend!
