Ted has 18 crayons. Terry has 47 crayons. How many crayons does they have in all?

  1. 45
  2. 55
  3. 65
  4. 75

hintHint:

Find by partial sum method.
To find partial sums add the digits in tens place and ones place seperately.

The correct answer is: 65


    Ted has 18 crayons. Terry has 47 crayons.
    Total crayon both have = 47 +18
    To find partial sums add the digits in tens place and ones place seperately.
    Partial sum of 47 + 18
    Step 1 : Add digits in tens and ones place seperately:
    40                                    07
    + 10                   and        + 08

    _____                             ______
    50                                        15
    Thus, the sum of 47 + 18 are 50 + 15 = 65.

    So, they have 65 crayons in all.
