    .89+.79+3.39+2.79
    Line the numbers up, centered around the decimal point.


       .89
       .79
     3.39
     2.79

    Put the decimal place in the answer space, directly under the ones in the column. Now add.


    9 + 9 + 9 + 9 = 4x9 =36   6 in the 100ths place, carry the 3
    3 + 8 + 7 + 3 + 7 = 28      8 in the 10ths place, carry the 2
    2 + 3 + 2 = 7                     7 in the 1s place  
    7.86 

    = 7.86


     


     

    Think of decimals as money, based upon ten and hundred, it you added this as if you had purchased items for those amounts, it may be easier for you.
