4.   An exhibition was visited by 174 people on first day, 236 people on second

                     day. How many people visited the exhibition in the two days?

                                                                H    T    O

               ADDITION  OF  4  DIGIT  NUMBERS  (WITHOUT  CARRYING)


               Now let us learn how to add any two 4-digit numbers without carrying.

               We arrange the digits in columns of thousands, hundreds, tens and ones.

               We write zero for vacant places.

               Now we add numbers in each column separately.

               Example 1:  Add 3212 and 5676

               Solution:                 Th    H    T    O

                                          3    2    1    2
                                     +    5    6    7    6

                                          8    8    8    8

                                   Add ones. → 2 + 6  =  8 ones.


                                   Add tens. → 1 + 7 =  8 tens.

                                   Add hundreds. → 2 + 6 =  8 hundreds.
                                   Add thousands. → 3 + 5 =  8 thousands.

                                   The sum = 8888.

                                                        EXERCISE 2.1



               Add the following numbers.


                     1.         Th    H    T    O   2.           Th   H     T   O    3.          Th    H    T    O

                                 4    0    2    5                6    4    6    3                 2    2    4    2

                            +    1    7    7    3           +    3    1    3    5            +    6    3    0    2
