Introduction:-
Sunita’s mother has 8 bananas. Sunita has to
go for a picnic with her friends. She wants to
carry 10 bananas with her. Can her mother
give 10 bananas to her? She does not have
enough, so she borrows 2 bananas from her
neighbour to be returned later. After giving
10 bananas to Sunita, how many bananas are
left with her mother? Can we say that she has
zero bananas? She has no bananas with her,
but has to return two to her neighbour. So
when she gets some more bananas, say 6, she
will return 2 and be left with 4 only.
Ronald goes to the market to purchase a pen. He has only 12 with him but the pen costs 15. The shopkeeper writes 3 as due amount from him. He writes 3 in his diary to remember Ronald’s debit. But how would he remember
whether ` 3 has to be given or has to be taken from Ronald? Can he express this
debit by some colour or sign?
Ruchika and Salma are playing a game using a number strip which is
marked from 0 to 25 at equal intervals.
To begin with, both of them placed a coloured token at the zero mark. Two
coloured dice are placed in a bag and are taken out by them one by one. If the
die is red in colour, the token is moved forward as per the number shown on
throwing this die. If it is blue, the token is moved backward as per the number
shown when this die is thrown. The dice are put back into the bag after each
move so that both of them have equal chance of getting either die. The one
who reaches the 25th mark first is the winner. They play the game. Ruchika
gets the red die and gets four on the die after throwing it. She, thus, moves the
token to mark four on the strip. Salma also happens to take out the red die and
wins 3 points and, thus, moves her token to number 3.
In the second attempt, Ruchika secures three points with the red die and
Salma gets 4 points but with the blue die. Where do you think both of them
should place their token after the second attempt?
Ruchika moves forward and reaches 4 + 3 i.e. the 7th mark.
Whereas Salma placed her token at zero position. But Ruchika objected
saying she should be behind zero. Salma agreed. But there is nothing behind
zero. What can they do?
Salma and Ruchika then extended the strip on the other side. They used a
blue strip on the other side.
