**
The important thing to remember when**
**adding or subtracting decimals in a vertical column**
**is to keep the decimals points in a column one directly**
**under another. For example**
**
23.56**
**
2.78**
** 7834.3**
** +
.003**

__the following is incorrect__**
23.56**
**
2.78**
**
7834.3**
**
+.003**

**Lets use a whole number example to clarify the**
**importance of placing digits in the proper place.**
**If you borrowed American dollars $150.00 from a friend and then**
**borrowed an additional $12.00 and your friend adds them**
**together in the following manner**
**
$150.00**
**
+$12.00**
