                  iDEntifying thE MathEMatical opErations

                  The process of identifying the mathematical operations involves deciding which
                  mathematical operation (addition, subtraction, multiplication, or division) will be useful

                  in solving a word problem.

                  example 1: Rachna had 12 ribbons. Her mother gave her 5 more ribbons. How many
                  ribbons does she have in all?

                  Solution:  Keyword used is 'in all'. So, choose the operation:

                                  +    –     ×     ÷         12 + 5 = 17 ribbons

                  example 2: Soni had a packet of 20 crayons. She lost 4 crayons at school. How many

                  crayons does she have left with?
                  Solution:  Keyword used is 'left'. So, choose the operation:

                                  +     –    ×     ÷         20 – 4 = 16 crayons

                  example 3: A pack of cards has 52 cards. How many cards will be there in 3 such packets?

                  Solution:   The value of '1 unit' is given. To find the value of 'more units', choose the
                                 operation:

                                  +     –    ×     ÷         52 × 3 = 156 cards

                  example 4: The cost of 8 oranges is `80. What is the cost of 1 orange?

                  Solution:   The value of 'more units' is given. To find the value of '1 unit', choose the

                                 operation:

                                  +     –    ×     ÷         `80 ÷ 8 = `10

                  98                                                                                    Mathematics-3
