May 18, 2020

GOOD  MORNING  STUDENTS! 😊😊


Welcome back to Maths  class.


Today, by the end of the lesson you will be able to:

 ➤ find the missing digits in the sums involving addition & subtraction.

Before we start next question, let us watch the following video to learn- how to find the missing digits in addition or click on the link
👉 https://youtu.be/-J8KJh7zb5E



Now, we shall start with Q1 of Ex-4.4(page no.49)

 Q1: Find the missing digits:
  (the digits in yellow are missing numbers) 

          1   
(a)       3 9 1 6 5   →      HINT: START ADDING FROM ONES PLACE
     +     2 6 1 4                5+4 = 9, AT ONES PLACE
          4 1 7 7 9                       6 + 1 =7, AT TENS PLACE .
                                                                         1 + 6 = 7, AT HUNDREDS PLACE
                                                          9 + 2 =11,SO 1 IS CARRIED TO THOUSANDS PLACE
                                                          1 + 3 =4  AT T-TH PLACE.
Solve (b) on your own.


We know that
SUBTRAHEND  +  DIFFERENCE  = MINUEND (for checking the answer)

So, here we will apply the same rule ( of addition) to find the missing digits in the sums involving subtraction.
(the digits in yellow are missing numbers)

(c)    5 6 8 1 8        Let's add subtrahend (smaller number) and Difference.
   -   2 1 6 2 0                Start adding from ones place
        3 5 1 9 8                 8 + 0 = 8 AT ONES PLACE
                                     9  + 2 = 11, So 1 is carried to HUNDREDS PLACE  
                                                 1 + 1 + 6 = 8 AT HUNDREDS PLACE
                                                 5 + 1 = 6 AT THOUSANDS PLACE
                                                 3 + 2 = 5 AT T-TH PLACE

HOMEWORK
Do Q1(d) of Ex-4.4 on your own.

That's all for today
Take Care
God Bless!!
